| Summary: | @) MCSS. Over the oceans, median brightness temperature 10 m s-I favor the formation of large, precipitation-sized 35-45 K below 225 K. Tropical Africa had the coldest median 85 GHz brightness temperature is related to the amount of ice and the most intense MCSs occurred more frequently in the April, July, and October 1993. An MCS was defined as an area at least 2000 km 2 of 85 GHz polarization corrected at sunset. In general, continental MCSs appeared to be based cloud climatologies and large scale seasonal dynamics. brightness temperatures < 250 K, with a minimum brightness cluster, organizing into multicellular mesoscale convective defined by the objective technique was consistent with IR- depression was 20-30 K below 225 K, while over land, it was distribution of MCSs between 35'N and 35'S for January, GHz channel to describe the size, intensity, and geographic ice, which strongly scatters upwelling 85 GHz radiation. The identify MCSs from the Special Sensor Microwave/Imager's 85 in an MCS and, indirectly, to the strength of the updrafts It has long been observed that tropical convection tends to largest median areas, 10 3 kM2 greater than other regions. MCSs tended to be colder at sunset than at sunrise, but minimum brightness temperature. The sub-tropical oceans had North America had the largest number of very large (> 1 0 5 oceanic MCSs tended to be marginally colder at sunrise than pool had the greatest number of MCSS. These regions also had producing the ice. This study used an objective technique to smaller and more intense than oceanic MCSS, and the largest sub-tropics. sunset than at sunrise. Both continental and oceanic MCSs sunset, and 60% more frequent over tropical continents at systems (MCS), In convective towers, updrafts on the order of temperature < 225 K. The distribution of the MCS population tended to be larger at sunrise than at sunset. Continental the smallest median areas. The sub-tropical oceans had the the warmest median minimum brightness temperatures. MCSs Tropical South America, tropical Afiica, and the oceanic wann were 35% more frequent over the oceans at sunrise than at |
