Abstract:

We consider an algorithm for identification of atmospheric gravity waves cloud views above water surface by MODIS imagery with 1000-m spatial resolution. Areas of the planet are outlined where these phenomena are the most frequent. Annual repeatability of atmospheric gravity waves сloud views is determined to the coasts of the Arabian Peninsula, and Australia, Mozambique Channel, and the Kurile Islands. We give a description of these phenomena identification algorithm based on Viola–Jones method. The cloud types, which forme atmospheric gravity waves cloud views are defined. The results of their identification in full-sized MODIS imagery of different planet regions are discussed.

Keywords:

atmospheric gravity waves, cloudiness, Haar-like features, pattern recognition, satellite data, stratification
