我们证明，从所谓的地球静止卫星“快速扫描”测量中推断的积云的发展速度是与深对流云相关的对流云顶垂直速度的良好代理。根据多功能运输卫星- 1R （MTSAT - 1R）观测到的夏季日本南部海域上空红外亮度温度的衰减率估算了对流云顶垂直速度。各高度的对流云顶垂直速度估计值的频率分布呈对数正态分布，与前人直接测量的统计特征一致。
We demonstrate that the rate of development of cumulus clouds, as inferred from the so‐called geostationary satellite “rapid‐scan” measurements, is a good proxy for convective cloud top vertical velocity related to deep convective clouds. Convective cloud top vertical velocity is estimated from the decreasing rate of infrared brightness temperature observed by the Multi‐functional Transport SATellite‐1R (MTSAT‐1R) over the ocean south of Japan during boreal summer. The frequency distribution of the estimated convective cloud top vertical velocity at each height is shown to distribute lognormally, and it is consistent with the statistical characteristics of direct measurements acquired in previous studies.
