  2. Climate of the Alps - Wikipedia

    en.wikipedia.org/wiki/Climate_of_the_Alps

    The climate of the Alps is the climate, or average weather conditions over a long period of time, of the exact middle Alpine region of Europe. [ 1 ] [ 2 ] As air rises from sea level to the upper regions of the atmosphere the temperature decreases .

  3. Cold-air damming - Wikipedia

    en.wikipedia.org/wiki/Cold-air_damming

    Cold air damming typically happens in the mid-latitudes as this region lies within the Westerlies, an area where frontal intrusions are common.When the Arctic oscillation is negative and pressures are higher over the poles, the flow is more meridional, blowing from the direction of the pole towards the equator, which brings cold air into the mid-latitudes.

    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 ...

    a) the alpine climate, which occurs when the mean biotemperature of a location is between 1.5 and 3 °C (34.7 and 37.4 °F). The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system.

  8. Weather forecasting - Wikipedia

    en.wikipedia.org/wiki/Weather_forecasting

    The difference between the forecast and the actual weather outcome for forecasts 3, 5, 7, and 10 days in advance. It was not until the 20th century that advances in the understanding of atmospheric physics led to the foundation of modern numerical weather prediction.

  9. Integrated Forecast System - Wikipedia

    en.wikipedia.org/wiki/Integrated_Forecast_System

    It comprises a spectral atmospheric model with a terrain-following vertical coordinate system coupled to a 4D-Var data assimilation system.In 1997 the IFS became the first operational forecasting system to use 4D-Var. [2] Both ECMWF and Météo-France use the IFS to make operational weather forecasts, but using a different configuration and resolution (the Météo-France configuration is ...
