Flowers are sprouting in January in New Hampshire, the Sierra Mountains in California are nearly snow-free, and lakes in much of Michigan still have not frozen. It's 2012, and the new year is ringing in another ridiculously wacky winter for the U.S. In Fargo, North Dakota yesterday, the mercury soared to 55°F, breaking a 1908 record for warmest January day in recorded history. More than 99% of North Dakota had no snow on the ground this morning, and over 95% of the country that normally has snow at this time of year had below-average snow cover. High temperatures in Nebraska yesterday were in the 60s, more than 30° above average. Storm activity has been almost nil over the past week over the entire U.S., with the jet stream bottled up far to the north in Canada. It has been remarkable to look at the radar display day after day and see virtually no echoes, and it is very likely that this has been the driest first week of January in U.S. recorded history. Portions of northern New England, the Upper Midwest, and the mountains of the Western U.S. that are normally under a foot of more of snow by now have no snow, or just a dusting of less than an inch. Approximately half of the U.S. had temperatures at least 5°F above average during the month of December, with portions of North Dakota and Minnesota seeing temperatures 9°F above average. The strangely warm and dry start to winter is not limited to the U.S--all of continental Europe experienced well above-average temperatures during December.

December 2011 jet stream pattern the most extreme on record
The cause of this warm first half of winter is the most extreme configuration of the jet stream ever recorded, as measured by the North Atlantic Oscillation (NAO). The Arctic Oscillation (AO), and its close cousin, the North Atlantic Oscillation (which can be thought of as the North Atlantic's portion of the larger-scale AO), are climate patterns in the Northern Hemisphere defined by fluctuations in the difference of sea-level pressure in the North Atlantic between the Icelandic Low and the Azores High. The AO and NAO have significant impacts on winter weather in North America and Europe--the AO and NAO affect the path, intensity, and shape of the jet stream, influencing where storms track and how strong these storms become. During December 2011, the NAO index was +2.52, which was the most extreme difference in pressure between Iceland and the Azores ever observed in December (records of the NAO go back to 1865.) The AO during December 2011 had its second most extreme December value on record, behind the equally unusual December of 2006. These positive AO/NAO conditions caused the Icelandic Low to draw a strong south-westerly flow of air over eastern North America, preventing Arctic air from plunging southward over the U.S. and Europe.




Figure 3. December 2011 temperatures in Europe and the U.S. were well above average, thanks to a positive phase of the Arctic Oscillation (AO). Compare the U.S. plot with the plot of typical departures of temperature from average due to the positive phase of the AO (Figure 4.) The two patterns are nearly identical. Image credit: NOAA/ESRL.

Wild swings in the December Arctic Oscillation
This winter's remarkable AO/NAO pattern stands in stark contrast to what occurred the previous two winters, when we had the most extreme December jet stream patterns on record in the opposite direction (a strongly negative AO/NAO). The negative AO conditions suppressed westerly winds over the North Atlantic, allowing Arctic air to spill southwards into eastern North America and Western Europe, bringing unusually cold and snowy conditions. The December Arctic Oscillation index has fluctuated wildly over the past six years, with the two most extreme positive and two most extreme negative values on record. Unfortunately, we don't understand why the AO varies so much from winter to winter, nor why the AO has taken on such extreme configurations during four of the past six winters. Climate models are generally too crude to make skillful predictions on how human-caused climate change may be affecting the AO, or what might happen to the AO in the future. There is research linking an increase in solar activity and sunspots with the positive phase of the AO. Solar activity has increased sharply this winter compared to the past two winters, so perhaps we have seen a strong solar influence on the winter AO the past three winters. Arctic sea ice loss has been linked to the negative (cold) phase of the AO, like we observed the previous two winters. Those winters both had near-record low amounts of sunspot activity, so sea ice loss and low sunspot activity may have combined to bring a negative AO.

The forecast for the remainder of January
We will (finally!) get the first major storm of 2012 in the U.S. early next week, when a low pressure system will develop over Texas and spread heavy rains of 1 - 3" along a swath from Eastern Texas to New England during the week. This storm will pull in a shot of cold air behind it late in the week, giving near-normal January temperatures to much of the country, and some snow to northern New England. Beyond that, it is difficult to tell what the rest of winter may hold, since the AO is difficult to predict more than a week or two in advance. The latest predictions from the GFS model show the current strongly positive AO pattern continuing for at least the next two weeks, resulting in very little snow and warmer-than-average temperatures. If we don't get significant snows during the latter part of winter, the odds of a damaging drought during the summer in the Midwest will rise. The soils will dry out much earlier than usual without a deep snow pack to protect them, resulting in a much earlier onset of summer-like soil dryness. Water availability may also be a problem in some regions of the west due to the lack of snow melt. Fortunately, most Western U.S. reservoirs are above average in water supply, due to the record-breaking snows of the previous winter.

NASA Finds Russian Runoff Freshening Canadian Arctic

"A new NASA and University of Washington study allays concerns that melting Arctic sea ice could be increasing the amount of freshwater in the Arctic enough to have an impact on the global "ocean conveyor belt" that redistributes heat around our planet.

The transpolar drift (purple arrows) is a dominant circulation feature in the Arctic Ocean that carries freshwater runoff (red arrows) from rivers in Russia across the North Pole and south towards Greenland. Under changing atmospheric conditions, emergent circulation patterns (blue arrows) drive freshwater runoff east towards Canada, resulting in freshening of Arctic water in the Canada Basin."


The full press release.

The findings in the Jan. 5 issue of the journal Nature.

So 103 years after an old record a new record is created, if we could have a say 10,300 year record of temperatures for every single inch of the planet I'm sure there would be extremes on both ends of the scale.

I'm still not fully convinced that "fossil fuels" have impacted the planet as much as some scientists say. How many major volcanic eruptions have their been in the past 103 years or 10,300 years. Tons of materials that can harm the ozone layer and affect climate are ejected in every eruption.

I wonder how much fossil fuel is spent on making one wind turbine, or electric car, or hybrid.

Every one of us depends on fossil fuel for transportation, heat, food, medicine, etc. We can't just give it all up.

I'm running off in a tangent though.

There just aren't enough facts for me to come to a definite conclusion, I'm still going to go with climate change is normal. We heat up, we cool down and repeat over and over.

That is all, time to sleep.

If you've been by my blog lately, you should have noticed that I took down my Tropical Cyclone Preliminary Report page. I decided that I'd rather post it directly here where everybody could read it. So, I thought I'd start with an interesting storm. I also made some changes to the storm's intensity. I will still have a huge blog over all the storms similar to Koritheman's sometime before the start of hurricane season. Here is Philippe's report:
------------------------------------------------
Philippe was a long-lived tropical cyclone that briefly attained Category 2 hurricane status on the Saffir–Simpson Hurricane Wind Scale. Although lasting for nearly two weeks, Philippe did not affect any landmasses.

a. Synoptic History

Hurricane Phillipe was first identified as a broad area of low pressure accompanying a tropical wave over western Africa in late September 2011. Tracking nearly due west, the system emerged into the eastern Atlantic Ocean late on 22 September. Gradual development took place as convection – thunderstorm activity – consolidated around the low-pressure area. At 0600 UTC on 24 September, the disturbance was sufficiently organized to be classified as a tropical depression while situated roughly 325 mi south of the Cape Verde Islands. As the depression continued to coalesce, the National Hurricane Center subsequently upgraded it to a tropical storm, receiving the name Philippe, 6 hr later.

Development of Philippe continued due to a light shear, warm sea surface temperature environment. By 0300 UTC on 25 September, the tropical storm had already reached an initial peak intensity of 50 kt. However, while tracking on a general west-northwest track around the southern periphery of a weakening mid-level ridge of high pressure, Philippe soon encountered an environment consisting of moderate wind shear. Westerly shear continued to increase over the following 48 hr, causing Philippe to weaken. Late on 27 September, Philippe's low-pressure area became well-removed from a small area of deep convection, and the system weakened to a tropical depression at 1800 UTC on 27 September. At this time, Philippe was situated roughly 755 mi west of the Cape Verde Islands.

Despite the hinderance of strong vertical wind shear impeding on the cyclone, deep convection abruptdly refired near the center, and Philippe re-intensified into a tropical storm 12 hr after weakened to a tropical depression. Continuing on a west-northwest track into the central Atlantic, Philippe remained a minimal tropical storm consisting of a partially exposed area of low pressure. The storm system reached a peak intensity of 60 kt early on 1 October 1 as it curved north-northwestward around the western periphery of the subtropical ridge. Shortly thereafter however, 40 kt of northerly wind shear began impacting the tropical storm, subsequently leading to a weakened cyclone once again.

Late on 3 October, Philippe turned west-southwest and eventually southwest as a mid-level ridge to its north strengthened. Phillipe gradually intensified due to a reprieve in wind shear, and a closed, well-defined eye became visible on mircowave imagery early on 4 October. During this time, convection became more circular and more intense; the storm was subsequently upgrade to a Category 1 hurricane at 0600 UTC on 4 October. While turning to the west in responce to an approaching large mid-latitude trough, Philippe weakened to a tropical storm 6 hr after intensifying into a hurricane. The system made a gradual, yet sharp turn towards the northwest and north between 5 October and 6 October.

While turning northward, Philippe abated for the final time, allowing Philippe to strengthen once again. The system strengthened to a Category 1 hurricane again by 0600 UTC on 6 October, and further intensified to reach its peak intensity of 85 kt, or minimal Category 2 hurricane status, by 0600 UTC on 7 October. Embedded within a deep southwesterly flow, Philippe turned towards the northeast while maintaining its peak intensity for nearly 24 hr. However, later on 7 October, Philippe began to weaken as 40 kt to 50 kt of wind shear began impeding on the system's development. The hurricane weakened to a tropical storm early on 8 October, while entering cooler sea surface temperatures. The system transitioned into an extratropical cyclone shortly thereafter as it merged with a cold front. The remnant cyclone was absorbed by a larger low-pressure area around 0300 UTC on 9 October about 600 mi west of the westernmost Azore Islands.

Chile burns on..still getting worse.

In southern Chile, six firefighters died while fighting a blaze that also left one civilian man dead. Two other firefighters were badly burned and one remains missing. Close to 50 wildfires have ripped through Chile, destroying hundreds of houses, forcing thousands to evacuate, and, causing millions of dollars in damage. Officials say, strong winds, unusually high temperatures and dry weather conditions have caused the spread of these fires. Authorities launched an investigation over suspicions of premeditated arson.

Mexican authorities are searching for a meteorite that fell to earth in a rural area in the northwestern part of the country, which was sighted in the region but about which there are as yet few details, officials said Friday. The alarm sounded when inhabitants of a mountainous region of Sinaloa state near the border with Chihuahua were startled by the approach of a luminous object in the night sky. NASA and Mexican emergency services agencies confirmed that the object was a meteorite, whose dimensions and exact place of impact are unknown. Some witnesses believed it could have crashed to earth between the Gustavo Diaz Ordaz Dam and the town of San Jose de Gracia. After hours of searching by air and land, an official of the Sinaloa municipality of Sinaloa, Marcial Alvarez, told Efe that the meteorite is believed to have impacted next door in Chihuahua state. This Saturday observers will fly over the area in search of the meteorite. It would not be the first time Sinaloa has seen a phenomenon like this. In 1871 a meteorite fell on the settlement of Bacubirito, which with a weight of 22 tons is considered one of the biggest in the world.

California's San Joaquin Valley is suffering through the longest period of air pollution in a dozen years. Since the beginning of December dirty air has exceeded federal health standards nearly every day.

The pollution is the unhealthiest kind - microscopic, chemical-laden particles that can get into lungs and absorbed into the bloodstream to create health risks in everyone, not just the young and infirm.

The valley is surrounded on three sides by mountains and the state's two major north-south highways cut through its interior. Cold temperatures and a lack of rain have trapped diesel exhaust and fireplace emissions.

Air officials are warning the public to limit outdoor activities.

UK scientists predict hottest summer in 2012
Global temperatures are likely to rise by nearly 0.5 degrees in 2012.

Enjoy the winter chill before scorcher summer sets in. The year 2012 may turn out to be among the top ten warmest years globally, and in the country, since 1850 - over 160 years.

The year is also expected to be warmer than the previous year, which was the ninth warmest year for India since 1901.

Weather scientists have predicted that 2012 is expected to be around 0.48 degree Celsius warmer than the average temperature or the long term global average.

Plains shatter warm weather records, set historic high temperatures
By Jason Samenow

High temperature records tied and broken across the U.S. Thursday (National Climatic Data Center) More than 300 record high temperatures were set in 21 U.S. states Thursday. But the heart of the unusual warmth concentrated in Plains, where some areas experienced temperatures 40 degrees above average.

Several locations set all-time January record high temperatures, including Huron (65 degrees) amd Mitchell (68 degrees) in South Dakota (SD) and Minot (61 degrees), Fargo (55 degrees) and Jamestown (56 degrees) in North Dakota. (Source: CapitalClimate).

What distinguishes this warm spell is the amount by which some records were broken. Consider Rapid City, SD hit 73, obliterating the old record by 13 degrees. (That 73 degree high temperature was 4 above the high temperature of 69 in Miami, Fl). Aberdeen, SD reached 63, smashing the old record of 46 by 17 degrees and setting a new monthly record.

AccuWeather highlighted the following incredible record: “...in Philip, S.D., the mercury reached a balmy 74 degrees, which absolutely obliterated the old record of 46 set back in 2002.”

In Minnesota, several locations reached the 60s for the first time ever during the first week of January. Alexandria reached 55, crushing its old record of 38 (from 1984) by an amazing 17 degrees (source: Star Tribune weather blog)

In Nebraska, record highs were set in Omaha (66), North Platte (69), Valentine (69) and Imperial (73, source: USA Today, AP). Sidney Nebraska’s record high of 74 broke the previous record of 62 and tied its monthly record.

Record highs were set by the numbers indicated on the map above. In some parts of northern Iowa, records were exceeded by more than 10 degrees. (hat tip: Capital Climate)Record highs were also set throughout the state of Iowa, several by at least 10 degrees.

Washington state weather blogger Cliff Mass tells us notable record heat was also experienced in the Pacific Northwest. More than a dozen locations set or tied record highs including Bend and Pendleton, Oregon, which climbed into the 60s.

Record warmth extended into California and the desert Southwest as well.

Across the U.S., almost one thousand high temperature records have been broken or tied this January, and more than 1,400 in the last week.

Wunderground’s Jeff Masters led his daily column this way: Flowers are sprouting in January in New Hampshire, the Sierra Mountains in California are nearly snow-free, and lakes in much of Michigan still have not frozen. It’s 2012, and the new year is ringing in another ridiculously wacky winter for the U.S.

The warm air mass in the Plains shifts east today towards the Ohio and Tennesse Valley, but will not produce as many records. The warmth in the Plains was enhanced by downslope flow off the Rocky mountains.

High-temperature records fall as winter fails to show in the Northland
We’re nearly halfway through the season and there’s not much sign of winter showing up at all. An entire society geared toward skiing, skating, sliding, shoveling and bundling against life-threatening wind chills has had to adapt to a winter normally seen in places like Des Moines.
