March 2013 was the globe's 10th warmest March since records began in 1880, according to NOAA's National Climatic Data Center (NCDC). NASA rated it the 9th warmest March on record. The year-to-date period of January - March has been the 8th warmest such period on record. March 2013 global land temperatures were the 11th warmest on record, and global ocean temperatures were the 9th warmest on record. March 2013 was the 337th consecutive month with global temperatures warmer than the 20th century average. Global satellite-measured temperatures in March 2013 for the lowest 8 km of the atmosphere were 12th or 8th warmest in the 35-year record, according to Remote Sensing Systems and the University of Alabama Huntsville (UAH), respectively. The Northern Hemisphere snow cover extent during March 2013 was the 16th largest in the 47-year period of record. Wunderground's weather historian, Christopher C. Burt, has a comprehensive post on the notable weather events of March 2013 in his March 2013 Global Weather Extremes Summary. He notes that one nation set an all-time heat record: on March 6th, Navrongo, Ghana reached 43.0°C (109.4°F), the warmest temperature reliably ever measured in the country (for any month.)


Figure 1. March 2013 was the 2nd coldest winter in the U.K. since 1910, exceeded only by March 1962. In this photo taken by wunderphotographer tonylathes on March 24, 2013, we see one of March's heavy snowstorms that affected Wardlow Village in Derbyshire, United Kingdom.


Figure 2. Departure of temperature from average for March 2013, the 10th warmest March for the globe since record keeping began in 1880. The Arctic Oscillation (AO), a large-scale climate pattern that can influence temperatures in the Northern Hemisphere, set a record low for March. This negative phase was associated with frigid Arctic air spilling southward into the Northern Hemisphere middle latitudes, leading to unusually cold conditions in the Eastern U.S., most of Europe, and northern Siberia.This phase of the AO also contributed to much warmer than average and even record warm temperatures in northeastern Canada and southeastern Greenland. A large swath of China and several regions in central and northern Africa in the 0°–20°N latitude belt were also record warm. Image credit: National Climatic Data Center (NCDC) .

First U.S. billion-dollar weather disaster of 2013: March 18 - 20 severe weather outbreak
Two billion-dollar weather disasters occurred globally in March, bringing the 2013 total to five, according to the March 2013 Catastrophe Report from insurance broker AON Benfield. The five billion-dollar weather disasters for 2013 so far:

1) Flooding in Indonesia, 1/20 - 1/27, $3.31 billion
2) Flooding in Australia, 1/21 - 1/30, $2.5 billion
3) Winter weather in Europe, 3/12 - 3/31, $1.8 billion
4) Drought in Central and Eastern China, 1/1 - 3/31, $1.71 billion
5) Severe weather in the Midwest U.S., 3/18 - 3/20, $1 billion

The first billion-dollar weather disaster in the U.S. was a severe weather outbreak that began on March 18, featuring a long-lived squall line of severe thunderstorms called a "derecho" that dropped hail up to softball size from Louisiana to South Carolina. Mississippi was hardest hit, with up to 60,000 insurance claims. Ten tornadoes touched down and two fatalities were reported during the outbreak. The U.S. has averaged 4.4 billion-dollar weather disasters per year from 1980 - 2012, but experienced 25 in the two-year period 2011 - 2012.

The deadliest March weather disaster was an outbreak of severe weather that swept across parts of eastern Bangladesh on March 22. The outbreak included a tornado that struck the regions of Sadar, Akhaura and Bijoynagar in Brahmanbaria district. At least 35 people were killed and 388 injured.


Figure 3. Hail up to the size of tennis balls fell on McComb, Mississippi, as documented by wunderphotographer sirencall On March 18, 2013. The hailstorm was part of a severe weather outbreak that gave the U.S. its first billion-dollar weather disaster of 2013.

Neutral El Niño conditions continue in the equatorial Pacific
For the 12th month in row, neutral El Niño conditions existed in the equatorial Pacific during March 2013. NOAA's Climate Prediction Center (CPC) expects neutral El Niño conditions to last through summer. The large majority of the El Niño models predict neutral conditions will last through the fall of 2013. Temperatures in the equatorial Eastern Pacific need to be 0.5°C below average or cooler for three consecutive for a La Niña episode to be declared; sea surface temperatures were 0.1°C below average as of April 22, and have been +0.1 to -0.4°C from average since March 1, 2013.

Arctic sea ice falls to 5th lowest March extent on record
Arctic sea ice extent during March reached its fifth lowest extent in the 35-year satellite record, according to the National Snow and Ice Data Center (NSIDC). This was the 10th consecutive March and 142nd consecutive month with below-average Arctic sea ice extent. The last ten years (2004 to 2013) have seen nine of the ten lowest March extents in the satellite record.

Why I spent as much time as possible outside today, with a lovely 68F temp and nothing but blue skies and sunshine! In any case, a commentary from the forecast discussion....

.CLIMATE...THE APRIL MONTHLY RAINFALL TOTAL AT SEATTLE TACOMA AIRPORT THROUGH THE 23RD IS 5.70 INCHES. THIS IS THE SECOND WETTEST APRIL ON RECORD AT THE AIRPORT SURPASSED ONLY BY THE 6.53 INCHES IN 1991. THE COMBINED JANUARY AND FEBRUARY PRECIPITATION AT SEA-TAC THIS YEAR WAS 5.74 INCHES. THERE HAVE ONLY BEEN TWO YEARS IN SEATTLE WEATHER RECORDS WHERE THE RAINFALL TOTAL FOR APRIL SURPASSED THE COMBINED JANUARY AND FEBRUARY PRECIPITATION TOTALS. AT SEA-TAC IN 1993...4.44 INCHES JANUARY AND FEBRUARY VERSUS 4.54 INCHES IN APRIL AND 1917 AT THE FEDERAL BUILDING 3.45 INCHES VERSUS 4.48 INCHES.

ELLIPTICAL MOON HALOS: The moon is waxing full, which means now is the time to be alert for icy moon halos. On April 22nd, Darryl Luscombe of Sointula, British Columbia, saw an unusual specimen. Instead of being circular, as usual, this halo was elliptical:

"I dont think I have ever seen an elliptical halo around the moon before," says Luscombe. "I looked up and just stared for about a minute. Then I raced inside to get my camera. I just managed to photograph it before it disappeared."

Atmospheric optics expert Les Cowley comments on the apparition: "There have been quite a few ellipticals seen in the last few weeks both in Europe and the US. Something strange [is happening] in all our skies!"

"These unusual ice halos are much smaller than the ordinary 22 degree halo encircling the sun or moon," Cowley continues. "In the 22 degree halo the ring is effectively made by light refracting through a 60 degree ice prism. The smaller elliptical halos need much narrower prisms and we think that six sided plate shaped crystals with very shallow pyramidal ends might do the work. The problem is that such crystals are unphysical and computer simulations using them do not predict the halo very well. An alternative is the wedge shaped sections of small snowflake-like crystals. Whatever their cause, they are rare and mysterious!"

Today is a very special day in our history.

Today is ANZAC Day.

ANZAC Day is a national day of remembrance in Australia and New Zealand that broadly commemorates all Australians and New Zealanders "who served and died in all wars, conflicts, and peacekeeping operations" and "the contribution and suffering of all those who have served. Originally 25 April every year was to honour the members of the Australian and New Zealand Army Corps (ANZAC) who fought at Gallipoli in the Ottoman Empire during World War I. Anzac Day marks the anniversary of the first campaign that led to major casualties for Australian and New Zealand forces during the First World War. The acronym ANZAC stands for Australian and New Zealand Army Corps, whose soldiers were known as Anzacs. Anzac Day remains one of the most important national occasions of both Australia and New Zealand, a rare instance of two sovereign countries not only sharing the same remembrance day, but making reference to both countries in its name.







They went with songs to the battle, they were young.
Straight of limb, true of eyes, steady and aglow.
They were staunch to the end against odds uncounted,
They fell with their faces to the foe.
They shall grow not old, as we that are left grow old:
Age shall not weary them, nor the years condemn.
At the going down of the sun and in the morning,
We will remember them.

Lest We Forget

Report: Vog makes for unhealthy Big Island air



HONOLULU (AP) – A new report by the American Lung Association gives the Big Island a failing grade for particle pollution in the air.

That’s because one of the island’s main sources of particle pollution is vog, or volcanic smog.

The association gave Hawaii County an F despite a decrease in the number of days with unhealthy particle pollution, from 23.5 days in the 2012 report to 12.5 days in this year’s report.

The annual report released Wednesday grades counties nationwide for ozone and particle pollution levels.

Honolulu is the only county in the state that collected data on ozone levels. There were no days of unhealthy levels of ozone, or smog.

Maui County received healthy grades for particle pollution. According to the report, there were incomplete data available for Kauai County.


Looks like SoCal in the 1960's....

After a few days of wet and unsettled weather, Hawaii appears to be in the drying trend. Trade winds will return by tomorrow and Friday, bringing in more settled weather. Earlier today, the heavy rain brought one to two inches of rain on the island of Oahu.

Maybe it was me, I tend to be on during the slow times of the blog. I actually hate posting during the height of hurricane season, when it gets crazy here I feel like I'm competing to get a word in. I generally hate competition or the atmosphere of competition outside of actual sports.

Hence why I would rather work low income jobs the rest of my life than being a businessman, lol.

During insane periods when say a major tropical cyclone threat exists for the U.S. coastline, I usually only throw in 1 or 2 comments. I wait until after it makes landfall when things slow down before I discuss more.

0358 AM CDT WED APR 24 2013

VALID 271200Z - 021200Z

...DISCUSSION...
A SPLIT/NEARLY ZONAL UPPER PATTERN WILL INITIALLY PREVAIL WITH SOME
TROUGH AMPLIFICATION POSSIBLE OVER THE NORTHWEST/NORTH-CENTRAL CONUS
BY LATE WEEKEND INTO EARLY NEXT WEEK. WHILE SOME SEVERE TSTMS WILL
PERIODICALLY BE POSSIBLE...RELATIVELY WEAK WESTERLIES ARE EXPECTED
SOUTH OF THE NORTHERN TIER OF THE CONUS...ESPECIALLY AS AN
INCREASINGLY BLOCKY/LESS PREDICTABLE PATTERN EVOLVES EARLY NEXT
WEEK.

FOR DAY 4/SATURDAY...AS A SHORTWAVE TROUGH IN THE SOUTHERN STREAM
CONTINUES EASTWARD/WEAKENS...A SEEMINGLY LIMITED SEVERE POTENTIAL
MAY EXIST ACROSS PORTIONS OF THE CENTRAL GULF COAST/SOUTHEAST
STATES. THERE MAY ALSO BE TSTMS...POSSIBLY SEVERE ON A LOCALIZED
BASIS...THIS WEEKEND /DAYS 4-5/ WITHIN A MOISTURE RETURN/UPSLOPE
REGIME IN AREAS SUCH AS SOUTHWEST TX/RIO GRANDE VICINITY.

OTHERWISE...MODEST LOW-LEVEL MOISTURE WILL GRADUALLY SPREAD
NORTHWARD ACROSS THE PLAINS AND INTO THE UPPER MIDWEST THROUGH LATE
WEEKEND/EARLY NEXT WEEK...WITH AID OF PERSISTENT LEE TROUGHING. AS
THE PREVIOUSLY MENTIONED UPPER TROUGH AMPLIFIES OVER THE
