Mesoscale processes are characterized by having a relatively large Rossby number compared to synoptic scale processes. Thus, over shorter distances as implicated in mesoscale phenomena, the importance of geostrophic balance and the Earth's rotation in shaping atmospheric processes is small relative to synoptic-scale phenomena.

In meteorology and climatology, a mesonet, portmanteau of mesoscale network, is a network of automated weather and, often also including environmental monitoring stations, designed to observe mesoscale meteorological phenomena and/or microclimates. [3] [4] Dry lines, squall lines, and sea breezes are examples
Convective mesoscale discussions are issued by the National Oceanic and Atmospheric Administration’s Storm Prediction Center based on the National Weather Center in Norman, Oklahoma. [ 1 ] [ 2 ] One type of mesoscale discussion is a meso-gamma mesoscale discussion , which are for tornadoes believed to be at least EF2 on the Enhanced Fujita ...
A mesoscale convective vortex (MCV), also known as a mesoscale vorticity center or Neddy eddy, [9] is a mesocyclone within a mesoscale convective system (MCS) that pulls winds into a circling pattern, or vortex, at the mid levels of the troposphere and is normally associated with anticyclonic outflow aloft, with a region of aeronautically ...
Mesoscale meteorology is the study of atmospheric phenomena that has horizontal scales ranging from 1 km to 1000 km and a vertical scale that starts at the Earth's surface and includes the atmospheric boundary layer, troposphere, tropopause, and the lower section of the stratosphere.
A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. Their area of cold cloud tops exceeds 100,000 square kilometres (39,000 sq mi) with temperature less than or equal to −32 °C (−26 °F); and an area of cloud top of 50,000 square ...
Fast radio bursts, strong pulses of energy detected in radio-wave frequencies, may be a common phenomenon in the cosmos, but their enigmatic origins are something astronomers are only beginning to ...
A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. They are long-lived, often form nocturnally, and commonly contain heavy rainfall , wind , hail , lightning , and possibly tornadoes .
