从卫星的角度预测对流开始（CI）提供了一个恒定的相对较高的时间和对流尺度的空间分辨率的工具，以帮助保护生命和财产预报员。通过监测红外（IR）通道亮度温度，其趋势和多光谱通道差异，可以在0-1小时的时间尺度上完成CI的预测。这些方法目前用于地球静止业务环境卫星系统，只是最近才在第二代气象卫星系统上进行了探索。MSG卫星上提供的额外通道和导出的不稳定指数可以提供对CI预测有用的额外信息。在本文中，一个概念的发展和讨论的优势和可能的应用，包括MSG特定的红外光谱通道和不稳定信息，通过分析几个对流的情况下，在中欧和南非。皇家气象学会
The prediction of convective initiation (CI) from a satellite perspective provides forecasters with a constant relatively high temporal and convective scale spatial resolution tool to help protect life and property. By monitoring infrared (IR) channel brightness temperatures, their trends and multi‐spectral channel differences, the prediction of CI can be accomplished on the 0–1 h timescale. These methods, currently employed on the Geostationary Operational Environmental Satellite (GOES) system, have only recently been explored on the Meteosat Second Generation (MSG) satellite system. The additional channels and derived instability indices available on the MSG satellites may provide additional information useful to the prediction of CI. In this paper a concept is developed and discussed towards the advantages and possible applications of the inclusion of MSG specific IR spectral channels and instability information through the analysis of several convective case events over Central Europe and South Africa.
