August 2012: Earth's 4th warmest August on record

August 2012 was the globe's 4th warmest August on record, according to the National Oceanic and Atmospheric Administration's National Climatic Data Center (NCDC). NASA rated August 2012 the 6th warmest on record. August 2012 global land temperatures were the 2nd warmest on record, and global ocean temperatures were the 5th warmest on record. August 2012 was the 330th consecutive month with global temperatures warmer than the 20th century average; the last time global temperatures were below average was February 1985. Global satellite-measured temperatures in August for the lowest 8 km of the atmosphere were 3rd warmest in the 34-year record, according to the University of Alabama Huntsville (UAH). Wunderground's weather historian, Christopher C. Burt, has a comprehensive post on the notable weather events of August in his August 2012 Global Weather Extremes Summary.

Most areas of the world experienced much higher-than-average monthly temperatures, including much of Canada, Southeast Europe, and Western Asia. Central Russia was much cooler than average.

El Niño watch continues
Sea surface temperatures were at 0.5°C above average as of September 17 in the equatorial Pacific off the coast of South America, and have been near or above the 0.5°C above average--the threshold needed for a weak El Niño event--since the beginning of July. However, winds, pressures, and cloud cover over the region have not responded in the fashion typically associated with an El Niño, and NOAA's Climate Prediction Center (CPC) classified conditions as being neutral in their September 6 El Niño discussion. They continued their El Niño watch, and gave a 69% chance that an El Niño event will be in place by the end of September. El Niño conditions tend to decrease Atlantic hurricane activity, by increasing wind shear over the tropical Atlantic. Wind shear has been close to average over the tropical Atlantic since the beginning of hurricane season in June. However, the past few runs of the GFS model have predicted a significant rise in wind shear over the Caribbean and tropical Atlantic by early October, which may represent El Niño finally beginning to kick in and affect the atmospheric circulation over the Atlantic.


Figure 2. Arctic sea ice extent as of September 18, 2012 (black line) compared to the previous record low years, in millions of square kilometers. This year's extent is far below any previous year, and is close to its minimum for the year. Satellite measurements of ice extent began in 1979. Image credit: Danish Meteorological Institute.

Arctic sea ice falls to all-time record low during August
August 2012 Arctic sea ice extent reached its lowest August extent in the 35-year satellite record, according to the National Snow and Ice Data Center (NSIDC). The new sea ice record was set on August 26, a full three weeks before the usual end of the melting season. Every major scientific institution that tracks Arctic sea ice agrees that new records for low ice area, extent, and volume have been set (see the comprehensive collection of sea ice graphs here.) Satellite records of sea ice extent date back to 1979, though a 2011 study by Kinnard et al. shows that the Arctic hasn't seen a melt like this for at least 1,450 years (see a more detailed article on this over at skepticalscience.com.) The latest September 18, 2012 extent of 3.5 million square kilometers is approximately a 50% reduction in the area of Arctic covered by sea ice, compared to the average from 1979 - 2000. The amount of open ocean exposed this September compared to September 1980 is about 43% of the size of the contiguous United States. The ice extent is close to its minimum for the year, and should start in increase within the next week or two, but that open water over the Arctic will provide a significant amount of heat and moisture to the atmosphere over the next few months that will significantly alter weather patterns. One possible impact may be an increase in the intensity and duration of extreme weather events during fall and winter.


Video 1. This animation shows the 2012 time-series of ice extent using sea ice concentration data from the DMSP SSMI/S satellite sensor. The black area represents the daily average (median) sea ice extent over the 1979-2000 time period. Layered over top of that are the daily satellite measurements from January 1 – September 14, 2012. A rapid melt begins in July, whereby the 2012 ice extents fall far below the historical average. Source: NOAA's Environmental Visualization Laboratory.

Nadine approaching the Azores
Long-lived Tropical Storm Nadine is headed northeastwards on a track that will bring the storm close to the Azores Islands on Wednesday and Thursday. A tropical storm watch has been posted for the islands of Flores and Corvo in the northwestern Azores. Steering currents for Nadine are expected to weaken on Wednesday, and the storm will move slowly and erratically for many days in the Central Atlantic late this week and early next week. On Friday, Nadine will become tangled up with an upper-level low pressure system, and the storm may partially or fully convert to an extratropical storm. By this weekend, the GFS and ECMWF models predict Nadine will move southwestward over warmer waters, and it could become fully tropical again.

Elsewhere in the Atlantic, thunderstorm activity associated with a tropical wave that moved through the Lesser Antilles Islands yesterday (92L) has diminished, and this wave is no longer a threat to develop. None of the reliable computers models is showing development of a new tropical cyclone in the Atlantic through September 24.

This is probably a stupid question, but does anyone know why they call it a "recurve" when it is curving north for the first time? Why don't cyclones just curve out to sea instead?

I don't think "recurve" is any kind of official weather term. It's just used as shorthand for a storm that was progressing in one direction curving off into another direction. "Curve" would certainly be more correct for what actually happens with a CV hurricane curving north and out to sea.

So far there have been 0 tornado reports, this probably will change but it's not an outbreak of tornadoes.

That was my impression also. We live with almost perpetual tornado watches from about February to April in Alabama. I wish the NWS and SPC would limit the number of tornado watches they issue. So few tornados result that it becomes the "boy who cried wolf" syndrome, and people tend to ignore them...and then get slammed when a tornado actually does develop.

"Sighs....." It looks like yet another recurve year for the majority of Cape Verde storms.


I think the only threat for the US now is late season homegrown stuff, although these also could be instigated by innoculous tropical waves. Look up the evolution of Hurricane Opal in 1995, which by the way was a recurve year for the most part.

Recurves arnt that bad.... i dont want any powerful storms htting the usa haha

opal..............Not a bad thing......OK?

??? I meant to emphasize (if you looked up the meteorological history of Opal) that Opal was formed in part by a tropical wave that came off Africa in the first half of September, and it didn't even warrant a care until it merged with another low over the Yucatan and started developing. Yes Opal was a bad storm that hit almost directly over where I live.

I mean more to emphasize the fact that only two storms have made it to the Caribbean without being sucked out to sea unlike a year like 2008, and that the coastlines have been spared from a destructive major hurricane Cape Verde storm such as Ivan in 2004 or maybe like Floyd in 1999.

Does anyone else think that 92l remnants could act as a seed for a storm when it gets in the Western Caribbean and near the Gulf of Mexico?

No. This front is bringing down lots of dry air and wind. Nothing is going to get started from any blobs for the next four or five days at least.

i got something i like to throw out there

if the arctic sea regions are ice free longer into the fall early winter
could that cause cold pools to dev over land areas
in the high artic
as oppose to the warmer areas of the open arctic sea to compensate for the ice loss

You probably hit the nail on the head with the ice pick on that one Keep.
The sea water temps will take a lot longer to drop than the land surface temps, so taking that into account, ice reformation will probably be delayed or possibly postponed in some areas.
I will keep an open mind on the Arctic open water subject for the time being but with sunset at the North Pole this week, things are still looking wet and slushy for a lot of ocean!

FORECAST FROM NWS FOR THE ANCHORAGE AREA ALASKA

Today: Periods of rain. Highs in the lower to mid 50s. Southeast wind 15 to 30 mph. Local gusts 40 to 50 mph...highest east anchorage...lower hillside...and eagle river. Along turnagain arm and higher elevations...southeast winds 35 to 55 mph with gusts 60 to 70 mph.

Tonight: Rain. Lows in the 40s. Along turnagain arm and higher elevations...southeast winds 35 to 55 mph with gusts to 70 mph increasing to 85 to 110 mph after midnight. Lower hillside...east anchorage...and eagle river...southeast winds 25 to 50 mph with gusts to 65 mph after midnight. Elsewhere...southeast 15 to 30 mph with gusts to 45 mph.

Wednesday: Rain. Highs in the 50s. Along turnagain arm and higher elevations...southeast winds 85 to 110 mph diminishing 60 to 85 mph in the afternoon. Lower hillside...east anchorage...and eagle river...southeast winds 25 to 50 mph with gusts to 65 mph through early afternoon. Elsewhere...southeast 20 to 35 mph with gusts to 45 mph.

110 MPH!!! that's nearly major hurricane force winds



But how long do the winds have to be sustained in these northern latitude storms to be recorded as maximum speeds?

Here in the UK, gales only have to sustain a wind speed for 10 seconds for it to be recorded as the official speed. In the case of tropical storms/hurricanes, I think the wind speed has to be maintained for a full minute.

As the condition is un-precedented in human recorded history, the answers would be highly theoretical and unreliable.

Good morning, what about the record ice in Anarctica and cold temps for September. This is the ice sheet you have to worry about melting since it's mainly over land and not in the ocean.
Where do people get this stuff? I guess they trust unreliable sources and are very gullible.

I went to this page:
http://data.giss.nasa.gov/gistemp/tabledata_v3/SH .Ts dSST.txt

The contents are a text file described by the header:
S.HEMI Land-Ocean Temperature Index in 0.01 degrees Celsius
base period: 1951-1980
sources: GHCN-v3 1880-08/2012 SST: 1880-11/1981 HadISST1

I pasted the data into my LibreCalc spreadsheet. After making a couple of corrections for an imperfect input, I sorted the data on the JJA Southern Hemisphere winter average temperature.

The result? 2012 was the 19th warmest winter since 1880.

I guess if there were a some record cold areas, it did not do much to influence the spatial average of the entire hemisphere.
