Abstract The results of studying a variability of internal-gravity-wave characteristics and their signatures based on satellite data are presented. Observations of the wave processes under study over the Russian Federation Pacific coast in the period from 2015 to 2017 are considered. High-periodic Himawari-8 satellite images and thematic products of their processing are used. The methods and algorithms for retrieving parameters of internal gravity waves and their cloud manifestations are described. Trends for various characteristics of wave processes under study are constructed. The typical variability of parameters of internal gravity waves and their signatures is revealed on the basis of the longest lasting episodes of their observation. The results of analysis of coefficients of correlation between the various characteristics of the wave processes under study are presented. Similar episodes of observing signatures of internal gravity waves for the time period under study are established. The processes occurring in the “atmosphere–underlying surface” system and their influence on the creation of favorable conditions for the generation and propagation of wave processes under study are discussed.

基于Himawari-8卫星数据的内部重力波云特征在其生命周期内的变异性研究

摘要 介绍了基于卫星数据研究内部重力波特征及其特征的变化的结果。考虑了 2015 年至 2017 年期间对俄罗斯联邦太平洋沿岸正在研究的波浪过程的观测。使用了高周期 Himawari-8 卫星图像及其处理的专题产品。描述了检索内部重力波参数及其云表现的方法和算法。构建了正在研究的波浪过程的各种特征的趋势。内部重力波参数的典型变化及其特征是根据其观测的最长持续时间段揭示的。介绍了所研究的波浪过程的各种特征之间的相关系数的分析结果。建立了在所研究的时间段内观察内部重力波特征的类似事件。讨论了“大气-下垫面”系统中发生的过程及其对为研究中的波浪过程的产生和传播创造有利条件的影响。
