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 include weather systems such as tropical cyclones, squall. Abstract. According to Zipser (), a mesoscale convective system (MCS) is a weather feature that exhibits moist convective overturning contiguous with or embedded within a mesoscale circulation that is at least partially driven by the convective by: Tropical Cyclogenesis and Mid-Level Vorticity David J.

A Scale-Discriminating Vorticity Budget for a Mesoscale Vortex in a Midlatitude, Continental Mesoscale Convective System Article in Journal of the Atmospheric Sciences 60(6) March Size. A mesoscale convective complex has either an area of cloud top of , km 2 or greater with temperature less than or equal to °C, or an area of cloud top of 50, km 2 with temperature less than or equal to °C. Size definitions must be met for 6 hours or greater. Its maximum extent is defined as when cloud shield reaches maximum area. (image Animation) A Mesoscale Convective Complex (MCC) formed late in the day on 07 July over Nebraska, and produced heavy rainfall amounts as it propagated southeastward across Kansas and Missouri during the nighttime hours. Early in the day on 08 July, the cold cirrus canopy of the MCC (cloud top temperatures less than C) rapidly dissipated as the system decayed.

Previous idealized simulations of convective systems have demonstrated that the development of mesoscale vortices within quasi-linear convective systems may be a natural consequence of the finite extent of the convective line, as horizontal vorticity is tilted into the vertical at the line ends. However, the source of this horizontal.

The remainder of this paper will focus on reviewing the characteristics, dynamics, and successful prediction of mesovortices. of crosswise horizontal vorticity generated in horizontal buoyancy gradients along the gust front. The develop-ment of a larger-scale (approximately hundreds of ki-lometers) midlevel cyclonic vortex in the stratiform re-gion of an asymmetric convective system owes largely to .
