Throughout 2012, there were 9,655 people killed by natural disasters, which marked the fewest global fatalities in a decade. This included 3,574 deaths related to hydrological events. The lower than usual death toll was due to fewer flooding and cyclonic events. Asia was the continent most often affected during the year. [2]
The software has been used to model real-time weather as well as seasonal forecasting of convection, tornadoes [3] and tropical cyclones. [4] The atmospheric modeling component of the software can be used with other atmospheric modeling software including the Weather Research and Forecasting Model , the Global Forecast System , and the ...
On December 24, the Storm Prediction Center (SPC) issued a moderate risk of severe weather, valid for the following day, as conditions became favorable for severe weather. The moderate risk covered an area stretching from west-central Louisiana to west-central Alabama [ 6 ] and was expanded south and west on December 25 to include cities such ...
It is the day of the month (04) followed by the time of day (1600 Zulu time, which equals 4:00 pm Greenwich Mean Time or 6:00 pm local time). 12012MPS indicates the wind direction is from 120° (east-southeast) at a speed of 12 m/s (23 knots; 27 mph; 44 km/h). Speed measurements can be in knots (abbreviated KT) or metres per second (abbreviated ...
The ENIAC main control panel at the Moore School of Electrical Engineering operated by Betty Jennings and Frances Bilas. The history of numerical weather prediction began in the 1920s through the efforts of Lewis Fry Richardson, who used procedures originally developed by Vilhelm Bjerknes [1] to produce by hand a six-hour forecast for the state of the atmosphere over two points in central ...
An example of a forecast product from the GFS, in this case a 96-hour forecast of 850 mb geopotential height and temperature. The Global Forecast System (GFS) is a global numerical weather prediction system containing a global computer model and variational analysis run by the United States' National Weather Service (NWS).

Microsoft's Aurora system offers global 10-day weather and 5-day air pollution (CO 2, NO, NO 2, SO 2, O 3, and particulates) forecasts with claimed accuracy similar to physics-based models, but at orders-of-magnitude lower cost. Aurora was trained on more than a million hours of data from six weather/climate models. [83] [84]
