Earth rainfall climatology Earth rainfall climatology Earth rainfall climatology Is the study of rainfall, a sub-field of Meteorology. Formally, a wider study includes water falling as ice crystals, i.e. hail, sleet, snow (parts of the hydrological cycle known as precipitation). The aim of rainfall climatology is to measure, understand and predict rain distribution across different regions of planet Earth, a factor of air pressure, humidity, topography, cloud type and raindrop size, via direct measurement and remote sensing data acquisition. Current technologies accurately predict rainfall 3–4 days in advance using numerical weather prediction. Geostationary orbiting satellites gather IR and visual wavelength data to measure
2005 United Kingdom snow events North Yorkshire received 20 cm of snow over high ground, whilst the snow caused huge tailbacks on the A1 between Alnwick and Berwick. The snow showers petered later on the 29th as outbreaks of rain, sleet and hill snow moved into western areas. On Friday 30 December, a band of heavy rain pushed eastwards, with heavy snow on the leading edge. This brought several hours of snow followed by rain, where 20 cm fell in some parts of Yorkshire, with snowdrifts of 1 metre reported. The snow caused hundreds of drivers to be stranded on the A1079 during the late
