The importance of deep convection in the tropics to the global circulation has been recognized for some time. In 1986 a pilot experiment termed the Equatorial Mesoscale Experiment (EMEX) was held off the northern coast of Australia to obtain measurements of the characteristics of deep convection in that part of the world and the effect of that convection on the larger scale environment. The Principal Investigator will produce quantitative descriptions of the wind, thermal and moisture profiles within and in the immediate environment of equatorial cloud clusters. Similarities and differences of the results from earlier field experiments will be noted and, if appropriate, new conceptual models developed. A major goal will be to investigate the effects on the large scales of motion of the vertical profile of latent heating and sea-air exchanges.

热带深部对流对全球环流的重要性已经被认识到一段时间了。1986年，在澳大利亚北部海岸外举行了一项名为赤道中尺度实验(EMEX)的试点实验，以测量该地区的深部对流特征以及这种对流对更大尺度环境的影响。首席调查员将对赤道云团内部和邻近环境中的风、热力和湿度分布进行定量描述。将注意到早期实地试验结果的相似和不同，并在适当的情况下开发新的概念模型。一个主要目标将是调查潜热和海-气交换的垂直剖面对大范围运动的影响。
