  of rain, lets first understand how it forms in the first place. There has always been the same amount of water on the earth, but the amount floating around in the air as water vapour or clouds depends on how warm it is. Warmer air holds more water while colder air holds less. This is an important

• Met Office Weather: Showers & sunshine expected midweek

  Wednesday morning will begin with locally heavy rain moving southeast across parts of England and Wales, accompanied by an area of showers pushing southeast. By mid-morning, the rain will clear the far southeast, leaving behind variable cloud cover and scattered showers. Temperatures will be around

• Parallel Suite 43 release notes

  Top level summary of PS43 PS43 introduces atmospheric physics upgrades to both the global and regional NWP models. In the global model there are changes to improve boundary-layer processes, the representation of cloud, radiation, warm rain microphysics, and deep convection, whilst in the regional

• Met Office daily weather: Largely fine and warm weekend

  While some areas will start off cloudy, particularly in the east, conditions are expected to improve as the days progress, offering ideal weather for outdoor events and activities. Saturday will begin with widespread cloud cover across Scotland, England, and eastern Wales, accompanied by hill fog

  . As it rises and cools, water vapour condenses to form clouds and perhaps precipitation. Consequently, the weather in a depression is often cloudy, wet and windy (with winds blowing in an anticlockwise direction around the depression). There are usually frontal systems associated with depressions. Figure
