Arctic sea ice volume now one-fifth its 1979 level

The stunning loss of Arctic sea ice extent in recent years is undeniable--satellite measurements have conclusively shown that half of the Arctic sea ice went missing in September 2012, compared to the average September during 1979 - 2000. But the extent of ice cover is not the best measure of how the fire raging in Earth's attic is affecting sea ice--the total volume of the ice is more important. But up until 2010, we didn't have the measurements needed to say how the total volume of ice in the Arctic might be changing. Scientists relied on the University of Washington PIOMAS model, which suggested that the loss of Arctic sea ice volume during September might be approaching 75% - 80%. The model results were widely criticized by climate change skeptics as being unrealistic. However, in April 2010, a new satellite called Cryostat-2 was launched, which can measure ice volume by beaming pulses of microwave energy off of the ice. With two years of data to Cryosat-2 data to analyze, the results of the PIOMAS model have now been confirmed by a study published on-line in February 2013 in Geophysical Research Letters. In a University of Washington news release, co-author Axel Schweiger said, "people had argued that 75 to 80 percent ice volume loss was too aggressive. What this new paper shows is that our ice loss estimates may have been too conservative, and that the recent decline is possibly more rapid." The U.K.'s Natural Environmental Research Council reported that the team of scientists found that from 2003 to 2012, the volume of Arctic sea ice declined 36% in the autumn and 9% in the winter. The measure of sea ice volume is a good indicator of how the Arctic's most stable, "multi-year" ice is fairing. As the multi-year ice declines, sea ice extent, the total area covered by sea ice, in an "Arctic death spiral". The new study shows that thick, multi-year ice has disappeared in areas north of Greenland, around the Canadian Archipelago, and to the northeast of Svalbard, Norway.

Why care about Arctic sea ice loss?
If you remove an area of sea ice 43% the size of the contiguous U.S. from the ocean, like occurred in September 2012, it is guaranteed to have a significant impact on weather and climate. The extra heat and moisture added to the atmosphere as a result of all that open water over the pole may already be altering jet stream patterns in fall and winter, bringing an increase in extreme weather events. The record sea ice loss in 2012 also contributed to an unprecedented melting event in Greenland. Continued sea ice loss will further increase melting from Greenland, contributing to sea level rise and storm surge damages. Sea ice loss will also continue to crank up the thermostat over Arctic permafrost regions. This will potentially release a significant fraction of the vast amounts of carbon currently locked in the permafrost, further accelerating global warming.

It took two years to get winter to return and now it does not want to leave. GFS Ensembles keep cooler than average temperatures across much of the East through early to mid-March.

The GFS wants to bring a major bomb of a storm into NW Australia in about 6 days. Other models are also showing something in that area, but strength, timing, and placement are inconsistent between the different models. The GFS is by far the strongest though, there'd be problems if this verified:



Definitely an area to watch in the coming days.

Haruna is very slowly approaching landfall, and continuing to maintain a large, ragged, cloudy eye:



As close as it is, it still likely has another day or so over water, but it probably won't strengthen, if anything it'll weaken.

According to the NWS in Wichita, the city has received 10 inches. Snow is still coming down very hard and is expected to do through the day.

HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE TALLAHASSEE FL
145 PM EST WED FEB 20 2013 /245 PM CST WED FEB 20 2013/

...POTENTIAL FOR SIGNIFICANT FLOODING LATE THIS WEEKEND AND INTO
NEXT WEEK...

RECENT HEAVY RAINFALL ACROSS THE REGION HAS ELEVATED RIVER LEVELS
ABOVE BASE FLOWS AND SATURATED SOILS ACROSS ALL OF SOUTHEASTERN
ALABAMA...SOUTHERN GEORGIA AND PORTIONS OF THE FLORIDA PANHANDLE.
RIVERS AND STREAMS ARE IN RECESSION AT THIS TIME BUT ARE NOT
EXPECTED TO RETURN TO BASE LEVELS BEFORE THE NEXT ROUND OF
RAINFALL BEGINS LATE THIS WEEK.

COMPUTER MODELS HAVE SOME DIFFERENCES WITH THE SPECIFIC DETAILS OF
HEAVY RAINFALL AMOUNTS FOR THE NEXT FEW DAYS. HOWEVER...CONFIDENCE
IS INCREASING THAT A COUPLE OF STORM SYSTEMS WILL AFFECT THE REGION
BEGINNING ON FRIDAY AND CONTINUE THROUGH AT LEAST TUESDAY. BECAUSE
THESE STORM SYSTEMS ARE EXPECTED TO BE SLOW MOVING AND PULL IN A
CONSIDERABLE AMOUNT OF GULF MOISTURE...THE POTENTIAL FOR A FLOOD
EVENT OF COMPARABLE MAGNITUDE OR GREATER THAN LAST WEEK IS
POSSIBLE INTO NEXT WEEK.

THE FIRST RAINFALL EVENT ON FRIDAY SHOULD CONTINUE INTO SUNDAY AND
HAVE THE POTENTIAL TO PRODUCE WIDESPREAD RAINFALL AMOUNTS OF 2 TO
4 INCHES ACROSS MUCH OF THE REGION. LOCALLY HEAVIER RAINFALL
TOTALS ARE POSSIBLE...ESPECIALLY ACROSS SOUTHEAST ALABAMA AND INTO
SOUTHWESTERN GEORGIA SHOULD THIS SYSTEM MOVE SLOWER THAN EXPECTED.

THE SECOND RAINFALL EVENT IS ANTICIPATED TO BEGIN ON MONDAY AND
LAST THROUGH TUESDAY. RAINFALL AMOUNTS WITH THIS SYSTEM ARE MORE
UNCERTAIN BUT COULD EASILY MEET OR EXCEED PREVIOUS RAINFALL FROM
THE FIRST EVENT.

AVERAGE STORM TOTAL RAINFALL AMOUNTS THROUGH TUESDAY...

SOUTHEAST ALABAMA.........5 TO 8 INCHES
FLORIDA PANHANDLE.........5 TO 8 INCHES
SOUTHWESTERN GEORGIA......3 TO 5 INCHES
SOUTH CENTRAL GEORGIA.....3 TO 4 INCHES
FLORIDA BIG BEND..........2 TO 4 INCHES

IT IS IMPORTANT TO NOTE THAT LOCALLY HEAVIER STORM TOTALS DOUBLE
THESE AVERAGE AMOUNTS ARE POSSIBLE.

WITH ALREADY SATURATED SOILS IN MANY LOCATIONS...RAINFALL AMOUNTS
OF THIS MAGNITUDE COULD CREATE ANOTHER ROUND OF DANGEROUS FLASH
FLOODING ACROSS SOUTHERN ALABAMA AND SOUTHWESTERN GEORGIA.

IMPACTS ON RIVERS...

SHOULD THESE ANTICIPATED RAINFALL AMOUNTS OCCUR...SIGNIFICANT RISES
ON AREA RIVERS AND STREAMS WOULD BE LIKELY. CURRENTLY...THE
FOLLOWING BASINS ARE WELL ABOVE BASE FLOWS AND VULNERABLE TO
FLOODING...

CHOCTAWHATCHEE...INCREASED FLOODING POTENTIAL BETWEEN GENEVA AND
BRUCE INTO NEXT WEEK.

CHIPOLA...INCREASED FLOODING POTENTIAL AT MARIANNA AND ALTHA INTO
NEXT WEEK.

APALACHICOLA...MINOR FLOODING POTENTIAL AT BLOUNTSTOWN CONTINUING
INTO NEXT WEEK.

FLINT...MINOR FLOODING POTENTIAL AT ALBANY AND AN INCREASED FLOOD
POTENTIAL FROM NEWTON TO LAKE SEMINOLE.

WITHLACHOOCHEE...MINOR FLOODING POTENTIAL AT VALDOSTA.

OTHER VULNERABLE STREAMS INCLUDE THE MUCKALEE CREEK AND
KINCHAFOONEE NORTH OF ALBANY AS WELL AS THE SPRING CREEK IN MILLER
COUNTY AND THE LITTLE RIVER NEAR HAHIRA.

AS WITH ANY HYDROLOGIC RIVER PREDICTION...RISES AND EVENTUAL CRESTS
ARE LARGELY DEPENDENT ON WHERE RAINFALL OCCURS AND ENTERS THE
BASIN. FOR THIS REASON...THIS OUTLOOK MAY BE UPDATED FREQUENTLY IN
THE NEXT FEW DAYS.

Stay safe with that much rain. Hope your crick behaves and stays in it's banks. We've more rain of course and more on the weekend. I just want it to dry out enough to be able to take the kids to recess at school.

I'll try to set up my streaming cam on the creek. Fingers crossed I still know how to hook it up.

Good morning, everyone. Evening, Aussie, if you're here. Seems a quiet morning. A warmer 53 degrees here in my part of Louisiana and a 50% chance of tornados today. Fun. Hopefully not until after school as getting ten special ed kindergarten boys to stay in storm position in the hallway is not easy.

Good morning. No big changes are expected from the mainly dry conditions for Puerto Rico.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
509 AM AST THU FEB 21 2013

.SYNOPSIS...SURFACE HIGH PRESSURE SYSTEM NORTH OF THE AREA...WILL
MOVE EAST OVER THE NEXT FEW DAYS. A WEAK FRONTAL BOUNDARY IS
EXPECTED TO APPROACH THE LOCAL AREA ON SUNDAY. ANOTHER SURFACE
HIGH PRESSURE WILL BUILD BEHIND THE FRONT TUESDAY.


&&

.DISCUSSION...PATCHES OF LOW LEVEL MOISTURE MOVED INTO THE AREA
TONIGHT AND PRODUCED SCATTERED SHOWERS ACROSS THE LOCAL AREA...BUT
ESPECIALLY ACROSS SOUTH AND SOUTHEASTERN PUERTO RICO. SOME OF
THESE SHOWERS LEFT ABOUT AN INCH OF RAIN ACROSS SOUTHEASTERN
PUERTO RICO. THESE SHOWERS ARE EXPECTED TO CONTINUE MOVING TO THE
WEST NORTHWEST THROUGH THE MORNING HOURS. THEN IN THE AFTERNOON
CLOUDINESS IS EXPECTED TO DEVELOP ACROSS PUERTO RICO AS THE FLOW
TURNS MORE EASTERLY AND THE CHANCE OF SHOWERS INCREASES ACROSS THE
WESTERN INTERIOR AND WESTERN SECTIONS OF PUERTO RICO.

FOR THE NEXT FEW DAYS...OVERNIGHT PASSING ISOLATED TO SCATTERED
SHOWERS ARE POSSIBLE ACROSS THE AREA UNTIL SUNDAY WHERE A WEAK
FRONTAL BOUNDARY MAY APPROACH THE AREA...BRINGING AN INCREASE IN
CLOUD COVER AND OVERALL SHOWER ACTIVITY. THEREAFTER...SHOWER
ACTIVITY IS ONCE AGAIN EXPECTED TO DECREASE AND REMAIN ISOLATED
AND LIGHT.

&&

.AVIATION...FLOW HAS BECOME EAST SOUTHEAST ACROSS PUERTO RICO AND
THE USVI. SHRA...MTN OBSCURATIONS AND MVFR CONDS ARE NOTED IN
SOUTHEAST PR AND LIKELY TO CONT THRU AT LEAST 21/12Z. RESIDUAL
MOISTURE DURING THE DAY WILL BRING LCL MVFR TO WRN PR AFT
21/17Z...DUE TO CIGS. EXPECT CLRG FROM E-W AFT 21/21Z. LLVL WIND
FLOW WILL BECOME EASTERLY AFT 21/21Z 10-20KT.


&&

.MARINE...SMALL CRAFT ADVISORY FOR THE ATLANTIC OFFSHORE WATERS
REMAINS IN EFFECT UNTIL 6 PM TODAY. SWELLS ARE SUBSIDING AND THE
LOCAL BUOYS ARE SHOWING THE DECREASE IN SEA HEIGHTS.
HOWEVER...SEAS ARE EXPECTED TO REMAIN UP TO 6 FEET BEFORE SEAS
INCREASE AGAIN EARLY NEXT WEEK.


&&

.PRELIMINARY POINT TEMPS/POPS...

If the NAO persists negative, trade winds get reduced & SSTs warm in tropics, while cooling off US coast, a trademark of big seasons.
