| Summary: | (IR) cloud top temperatures are related to cloud-to-ground 1993. Data from TOGA COARE provide the opportunity for 8.0 km layer, and a slower decrease with height, both and non-lightning producing cells. Lightning producing compared, and the cases ranked by mean flashes per 10000 km2. comprehensive studies of tropical oceanic convection. This continental convection. In fact, the highest flash rate for convective cells have higher radar reflectivity in the 5.0 - convective cores within the MCSs, as well as their infrared For selected cases, radar/lightning overlays and vertical indicate a pronounced difference between lightning producing indicate the highly variable nature of the TOGA COARE MCSs. individual VPRR and of all convective VPRR from the 13 cases lightning activity and cold cloud area. The properties of lightning due to the lack of a clear relationship between the lightning. IR and lightning time histories for each case are lightning.

When a system did produce lightning, more flashes generally occurred during its growth phase. observations indicating larger ice particles in the mixed order of magnitude less cloud-to-ground lightning than order to describe the convective structures of cells that overall flash rates of the TOGA COARE MCSs support previous Overall, IR measurements seem to be a poor indicator of Pacific warm pool region from November 1992 through February phase region between 00 C and -200 C. produced lightning, and also cells that did not produce profiles of maximum radar reflectivities (VPRRs) are shown in size of cold cloud-top area and cloud-to-ground flashes. The Some MCSs which have very cold cloud-top temperatures have study seeks to understand more about the structures of Texas MCS study (Toracinta et al. 1995). Examination of the 13 cases was less than the weakest continental case in a The TOGA COARE experiment was carried out in the western tropical mesoscale convective systems in relation to their work which showed that tropical oceanic convection has an |
