ECMWF: Global weather forecast model from the "European Centre for Medium-Range Weather Forecasts". ECMWF is now running its own Artificial Intelligence/Integrated Forecasting System (AIFS) as part of its experiment suite. These machine-learning-based models are very fast, and they produce a 10-day forecast with 6-hourly time steps in approximately one minute.

RH 700 hPa:
700百帕等压面相对湿度

描述:

这幅图反映700百帕等压面的相对湿度。在槽前或锋区附近，暖空气被抬升。当上升空气冷却时，其相对湿度增加，有时导致水汽凝结，形成云。这个过程称为锋面抬升。700百帕(相当于3000米左右高度)高相对湿度区说明当地有抬升，因此是天气活跃区。
