Sea, Lake, and Overland Surges from Hurricanes (SLOSH)

nhc.noaa.gov

SLOSH Model - Introduction

The Sea, Lake and Overland Surges from Hurricanes (SLOSH) model is a computerized numerical model developed by the National Weather Service (NWS) to estimate storm surge heights resulting from historical, hypothetical, or predicted hurricanes by taking into account the atmospheric pressure, size, forward speed, and track data. These parameters are used to create a model of the wind field which drives the storm surge.

The SLOSH model consists of a set of physics equations which are applied to a specific locale's shoreline, incorporating the unique bay and river configurations, water depths, bridges, roads, levees and other physical features.

Heat Waves Could Be Predicted Weeks in Advance, Study Finds

Scientists have discovered a weather pattern that foreshadows heat waves and could be used to predict them more than two weeks in advance, well beyond the 10-day range of weather forecasts, a new study reports.

Researchers at the National Center for Atmospheric Research wondered if the prolonged and often deadly heat waves that hit the United States and other Northern Hemisphere countries during the summer could be triggered by large-scale atmospheric circulation patterns.

Is Weird Winter Weather Related to Climate Change?

NASA Goddard Space Flight Center
The polar jet stream may be driving a "hemispheric pattern of severe weather."

Scientists are trying to understand if the unusual weather in the Northern Hemisphere this winter — from record heat in Alaska to unprecedented flooding in Britain — is linked to climate change. One thing seems clear: Shifts in the jet stream play a key role and could become even more disruptive as the world warms.

This winter’s weather has been weird across much of the Northern Hemisphere. Record storms in Europe; record drought in California; record heat in parts of the Arctic, including Alaska and parts of Scandinavia; but record freezes too, as polar air blew south over Canada and the U.S., causing near-record ice cover on the Great Lakes, sending the mercury as low as minus 50 degrees Celsius in Minnesota, and bringing sharp chills to Texas.

In the nation's capital, agencies shuttered their doors as the area got up to 11 inches of snow.

The snowfall in Philadelphia was expected to reach 11 inches, while New Yorkers were experiencing what probably will be 15 inches of snow.

In the South, states sprang into cleanup mode as power outages mounted and hundreds of thousands of customers shivered through a cold, dark night.

Historic Freeze - Polar Vortex Could Break Temperature Records

It has been decades since parts of the Midwest experienced a deep freeze like the one expected to arrive Sunday, with potential record-low temperatures heightening fears of frostbite and hypothermia even in a region where residents are accustomed to bundling up.

This "polar vortex," as one meteorologist calls it, is caused by a counterclockwise-rotating pool of cold, dense air. The frigid air, piled up at the North Pole, will be pushed down to the U.S., funneling it as far south as the Gulf Coast.

E. Coli, Oil Spills and Airlifts: Fallout from Colorado Flooding Continues

cnn.com - by Greg Botelho and Elwyn Lopez - September 20, 2013

(CNN) -- Efforts continued Friday to cope with fallout from flooding that''s rocked the Rocky Mountain state -- including more airlifts of stranded residents, discoveries of oil spills and a plea to one town's residents to stay away until E. coli is cleared from their tap water.
