California’s Storm: The Coolest View You Will See Today. Scientists debunk climate change myths. Wits University scientists have debunked two big myths around climate change by proving firstly, that despite predictions, tropical storms are not increasing in number.
However, they are shifting, and South Africa could be at increased risk of being directly impacted by tropical cyclones within the next 40 years. Secondly, while global warming is causing frost to be less severe, late season frost is not receding as quickly as flowering is advancing, resulting in increased frost risk which will likely begin to threaten food security. According to Jennifer Fitchett, a PhD student in the Wits School of Geography, Archaeology and Environmental Studies (GAES), there has been an assumption that increasing sea surface temperatures caused by global warming is causing an increase in the number of tropical cyclones. The big surprise came when Fitchett and Grab looked at where storms have been happening. South Africa is already feeling the effects of this shift. If Yellowstone Could Talk, It Might Squeak.

A storm left tens of thousands of people in Britain without power Thursday and one man dead, adding to the misery that began with heavy rains back in December. Parts of England have been underwater for more than six weeks now, since storms began pummeling the west of Great Britain around Christmas.
Now the floodwaters are lapping near Windsor Castle, as the Thames overflows its banks. You needn't travel far from central London to find the misery: A 20-minute train ride from the city brings you to West Byfleet.

Warming Arctic May Be Causing Jet Stream To Lose Its Way : The Two-Way. Hide captionThe jet stream that circles Earth's north pole travels west to east.
But when the jet stream interacts with a Rossby wave, as shown here, the winds can wander far north and south, bringing frigid air to normally mild southern states.

Getting Better At Predicting The Weather. After a brutal week of winter storms, the meteorological community is trying to improve the way weather is studied, predicted and communicated to the public.

Anatomy of a Super Typhoon — NOVA Next. By any measure, Super Typhoon Haiyan was one of the most extraordinary tropical cyclones in world history.
Tropical cyclones rarely reach Category 5 strength, when wind speeds exceed 155 mph. In fact, an average of just four Category 5 storms occur globally each year. But as Haiyan hurtled westwards towards the Philippines across the warm waters of the West Pacific Ocean during the first week of November 2013, the storm fed off the deepest region of warm waters anywhere on the planet, rapidly intensifying into a Category 5 storm. A Ridge with a Cloud on Top. Storm with 100 mph gusts hits soggy Britain - Weather, forecasts, news, blogs and maps. Updated: 2/12/2014 The Met Office said in a paper published this week that "there is no definitive answer" on the role played by climate change in the recent weather and floods.
British Prime Minister David Cameron called an emergency meeting to discuss response to the worsening floods throughout Britain, which are forcing some residents to evacuate. Photo: AP, February 12, 2014 LONDON — Britain's weather service says it sees the tentacles of climate change in a spate of storms and floods battering the country, but has stopped short of saying warming directly caused the extreme storms.
The latest round of bad weather hit Britain's west coast Wednesday with winds gusting at more than 100 miles (160 kilometers) an hour. Science Behind The News: Tornadoes.
