Mesoscale meteorology. Mesoscale meteorology is the study of weather systems and processes at scales smaller than synoptic-scale systems but larger than microscale and storm-scale. Horizontal dimensions generally range from around 5 kilometres (3 mi) to several hundred kilometers. Examples of mesoscale weather systems are sea breezes, squall ...
A mesoscale convective system ( MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persists for several hours or more. A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and ...
The Weather Prediction Center serves as a center for quantitative precipitation forecasting, medium range forecasting (three to eight days), and the interpretation of numerical weather prediction computer models . The Weather Prediction Center issues storm summaries on storm systems bringing significant rainfall and snowfall to portions of the ...
This is a list of meso-gamma mesoscale discussions, which are issued by the National Oceanic and Atmospheric Administration’s Storm Prediction Center during high-confidence and high-impact severe weather events.

A mesocyclone is a meso-gamma mesoscale (or storm scale) region of rotation ( vortex ), typically around 2 to 6 mi (3.2 to 9.7 km) in diameter, most often noticed on radar within thunderstorms. In the northern hemisphere it is usually located in the right rear flank (back edge with respect to direction of movement) of a supercell, or often on ...
A mesoscale convective complex has either an area of cloud top of 100,000 km 2 or greater with temperature less than or equal to −32 °C, or an area of cloud top of 50,000 km 2 with temperature less than or equal to −52 °C. Size definitions must be met for 6 hours or greater. Its maximum extent is defined as when cloud shield reaches ...
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 ...
