  2. Climate of Tunisia - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Tunisia

    Tunisia is the eighteenth most water stressed country in the world. Tunisia's climate is divided into seven bioclimatic zones, with the main difference between the north and the rest of the country being due to the Tunisian hills which separate the regions subject to a Mediterranean climate and a typical hot desert climate of the Sahara - the largest hot desert in the world.

    monthly forecasts, predicting the weather on a weekly basis 30 days ahead; seasonal forecasts up to 12 months ahead. Over the past three decades ECMWF's wide-ranging programme of research has played a major role in developing such assimilation and modelling systems. This improves the accuracy and reliability of weather forecasting by about a ...

    Christopher C. Burt, a weather historian writing for Weather Underground, believes that the 1913 Death Valley reading is "a myth", and is at least 2.2 or 2.8 °C (4 or 5 °F) too high. [13] Burt proposes that the highest reliably recorded temperature on Earth could still be at Death Valley, but is instead 54.0 °C (129.2 °F) recorded on 30 ...

    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]

    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).

    en.wikipedia.org/wiki/Quantitative_precipitation...

    Within the United States, the Hydrometeorological Prediction Center, [20] River Forecast Centers, [1] and local forecast offices within the National Weather Service create precipitation forecasts for up to five days in the future, [21] forecasting amounts equal to or greater than 0.01 inches (0.25 mm). Starting in the mid-to-late 1990s, QPFs ...

    The neighborhoods surrounding the Profitis Ilias in Mikri Mantineia were left without electricity for over 20 days after extensive damage occurred to the power grid. [13] Strong waves damaged seaside businesses and flooded streets in Kalamata, Messinia. [14] Traffic along coastal roads from Kalamata to Filoxenia ceased during the storm. [15]
