Study: Jump in lightning may be precursor to severe weather

January 19th, 2015 at 8:31 pm by under Weather

Sudden jump in a storm's lightning might warn a supercell is forming

A jump in lightning strikes inside a thunderstorm might be a severe weather early warning, says research by Sarah Stough, a UAH graduate student in atmospheric science. Credit: UAH

A sudden jump in the number of lightning strikes inside a garden-variety thunderstorm might soon give forecasters a new tool for predicting severe weather and issuing timely warnings, according to research at The University of Alabama in Huntsville (UAH).

The sudden increase in lightning is one sign a normal storm is rapidly evolving into a supercell, with a large rotating updraft – or mesocyclone – at its heart.

“Supercells are more prone to produce  events, including damaging straight line winds and large hail,” said Sarah Stough, a UAH graduate student in atmospheric science. “Supercells also produce the strongest and most deadly tornadoes.”

Early results from Stough’s research were scheduled to be presented Wednesday, Jan.7, in Phoenix at the American Meteorological Society’s annual meeting.

NASA launches soil-sensing satellite

January 18th, 2015 at 8:08 pm by under Weather

(NASA.gov):  A new NASA satellite that will peer into the topmost layer of Earth’s soils to measure the hidden waters that influence our weather and climate is in final preparations for a Jan. 29 dawn launch from California.

The Soil Moisture Active Passive (SMAP) mission will take the pulse of a key measure of our water planet: how freshwater cycles over Earth’s land surfaces in the form of soil moisture. The mission will produce the most accurate, highest-resolution global maps ever obtained from space of the moisture present in the top 2 inches (5 centimeters) of Earth’s soils. It also will detect and map whether the ground is frozen or thawed. This data will be used to enhance scientists’ understanding of the processes that link Earth’s water, energy and carbon cycles.

Costliest Weather Events Of 2014

January 17th, 2015 at 7:04 pm by under Weather

In 2014, there were 8 weather and climate disaster events with losses exceeding $1 billion each across the United States. These events included a drought event, a flooding event, 5 severe storm events, and a winter storm event. Overall, these events resulted in the deaths of 53 people and had significant economic effects on the areas impacted. Further cost data and figures on individual events in 2014 will be announced in mid-2015.

2014-Billion-Dollar-Disasters-map

1.  The Western Drought (1/1/14 – 12/31/14)  -  Historic drought conditions affected the majority of California for all of 2014 making it the worst drought on record for the state. Surrounding states and parts of Texas and Oklahoma also experienced continued severe drought conditions. This is a continuation of drought conditions that have persisted for several years.

2.  Rockies/Plains Severe Weather (9/29/14 – 10/2/14)  -  Severe storms across the Rockies and Plains states (CO, TX, KS). Large hail and high winds created significant damage across eastern Colorado and Texas, particularly in the Dallas metro area.

3.  Michigan/Northeast Flooding (8/11/14 – 8/13/14)  -  Heavy rainfall in excess of 5 inches caused significant flooding in cities across Michigan damaging thousands of cars, business, homes and other infrastructure. Flooding also occurred across Maryland and New York’s Long Island, as the slow-moving storm system delivered 24-hour rainfall exceeding 6 and 12 inches, respectively, creating more flood damage. Islip, NY received 13.57 inches of rain over a 24-hour period on Aug 12-13 setting a new 24-hour precipitation record for New York.

4.  Rockies/Central Plains Severe Weather (6/3/14 -6/5/14)  -  Severe storms across the Rockies and Central Plains states (NE, KS, WY, IA, AR). Wind gusts exceeding 90 mph and baseball to softball sized hail caused severe damage to structures and vehicles in central and eastern Nebraska.

5.  Rockies/Midwest/Eastern Severe Weather (5/18/14 – 5/23/14)  -  Severe storms across the Rockies, Midwest and Eastern states (CO, MT, IA, IL, IN, OH, SC, VA, PA, DE, NY) with the most costly damage in Colorado, Illinois and Pennsylvania.

6.  Midwest/Southeast/Northeast Tornadoes and Flooding (4/27/14 – 5/1/14)  -  Tornado outbreak across the Midwest, Southeast and Northeast states (AL, AR, DE, FL, GA, KS, MD, MO, MS, NC, NJ, NY, PA, TN, VA) with 83 confirmed tornadoes. Mississippi had its 3rd greatest number of tornadoes reported for any day since 1950. Torrential rainfall in the Florida panhandle also caused major flooding, as Pensacola set new 1-day and 2-day precipitation records of 15.55 and 20.47 inches, respectively. Flooding rains were also reported in coastal Alabama, as Mobile received 11.24 inches of rain, the third greatest calendar day rainfall total for the city.

7.  Plains Severe Weather (4/2/14 – 4/3/14)  -  Severe storms across the Plains states (IL, KS, MO, TX) causing considerable hail and wind damage in Texas.

8.  Midwest/Southeast/Northeast Winter Storm (1/5/14 -1/8/14)  -  Winter storm caused widespread damage across numerous Midwest, Southeast and Northeastern states (AL, GA, IL, IN, KY, MD, MI, MO, MS, NC, NJ, NY, OH, PA, SC, TN, VA).


2014: Earth’s hottest year on record

January 16th, 2015 at 11:04 am by under Weather

This animation shows Earth’s surface temperature in 2014 compared to the 1981-2010 average, followed by monthly maps of difference from average temperatures for each month January through December 2014. Maps are based on data from NOAA’s National Climatic Data Center.

In 2014, the combined land and ocean surface temperature was 1.24°F (0.69°C) above the 20thcentury average, making the year the warmest since records began in 1880. The ocean alone was record warm, while the land alone was fourth warmest.  Five months set new records for warmth: May, June, August, September, and December.  October tied for record warmest.

The 20 warmest years in the historical record have all occurred in the past 20 years. Except for 1998, the 10 warmest years on record have occurred since 2002.

 

Annual temperatures since 1880 compared to the twentieth-century average.  The ten warmest years on record (darkest red) have occurred in the most recent decades. Graph by NOAA Climate.gov, based on data from the National Climatic Data Center.

January bird forecast

January 15th, 2015 at 11:28 pm by under Weather

What to watch for in January: Hungry feathered friends

Here’s the Central Texas bird forecast for the month, courtesy of Travis Audubon. Learn more about Central Texas birds and bird-related events for all ages at travisaudubon.org or by calling 512-300-BIRD. Travis Audubon is on Twitter and Facebook. Follow us on Twitter @TravisAudubon and give us a like at www.facebook.com/travisaudubon.

A little help for our friends

Now is a great time to feed the birds. A little extra fat and protein from seeds and suet will help your common winter birds get through the cold nights.

Suet is available in blocks at big hardware stores and bird-friendly businesses, such as Wild Birds Unlimited. If you have a problem with squirrels, look for red pepper suet, which they avoid. Suet will attract woodpeckers, wrens, blue jays and titmice, but other cool birds like wintering warblers have been known to take a bite.

Want to make your own suet? Check out this site for recipes and instructions: http://www.sialis.org/suet.htm. Find a PDF guide from the Cornell Lab of Ornithology about feeding birds in winter at http://bit.ly/1K2x01u.

Find more advice about nonseed snacks you can put out for your birds at http://www.allaboutbirds.org/Page.aspx?pid=1180.

Don’t forget the water, with a bird bath or even just a shallow dish or planter saucer on the ground.

Who might visit your feeders this time of year? Some of our cutest birds: the Carolina Chickadee and the Black-crested Titmouse.

The chickadee is a small bird with a black-and-white head, gray body, and tiny beak. They have relatively large heads and short necks, which makes them appear rather spherical, even when they are not puffed up in cold weather. They love seeds and are quite acrobatic, grabbing seeds and zipping off to a nearby branch to eat.

They are often seen with another small but charming bird, the titmouse. These birds are somewhat larger but are equally energetic and acrobatic. They are mostly gray with a black crest and big black eyes and a dark beak.

NOAA/NASA expected to announce 2014 as hottest year on record

January 14th, 2015 at 7:52 pm by under Weather

A major announcement is expected this Friday from NOAA and NASA, potentially declaring 2014 as the hottest year on record around the globe.

  • This means that 13 of the hottest years on record globally (since 1880) have all happened in the past 15 years
  • The odds of that happening by chance are less than 1-in-27 million

2014 Was the Hottest Year on Record
NOAA and NASA Joint Announcement on Friday

This Friday, NOAA and NASA will officially declare 2014 as the hottest year in 134 years of record keeping, with an expected annual global temperature 0.68°C above the 20th century average according to NOAA’s dataset.

In 2014, seven out of 12 months tied or topped previous monthly global temperature records. Oceans in particular experienced record warmth, with seven consecutive months—May through November—setting new records for surface ocean heat.  Most importantly, 2014 sets the new global temperature record in the absence of an El Niño, a phenomenon which raises global temperature. Many of the previous hottest years on record have occurred during El Niño years, including 2010 and 2005, which now share the record for second hottest year.

2014 brings second-lowest inflows on record to Highland Lakes

January 13th, 2015 at 7:24 pm by under Weather

blog

LCRA — Inflows into the Highland Lakes from streams and tributaries in 2014 were the second lowest for any year since 1942, when Mansfield Dam was completed.

In December, the amount of water flowing into the Highland Lakes totaled just more than 10,500 acre-feet – about 16 percent of the historical average for inflows for the month of December. (An acre-foot of water is 325,851 gallons.)

Unlike the Austin area, which had above-average rainfall last year, the Highland Lakes watershed in the Texas Hill Country had below-normal rainfall in 2014 and remains in a serious drought. The intermittent timing of storms in the Hill Country allowed the soil to dry out between rain events, which resulted in little runoff into the lakes. For water to flow into the lakes, the rain must fall on saturated ground, or the rain must be hard enough to generate substantial runoff. Very little of either occurred in 2014.
