To understand the relationship among easterly waves, tropical cyclones (TCs), and the large‐scale environment, a robust climatology of easterly waves for the tropical Western Hemisphere has been developed. The foundation for the climatology is a new easterly wave tracking algorithm that identifies westwards propagating disturbances over the tropical East Pacific, Atlantic, and Africa. To assess the issue of track dependencies and easterly wave representation, climatologies are prepared separately from the NCEP‐NCAR, CFS‐R, ERA‐40, and ERA‐Interim reanalyses. The source code for the easterly wave‐tracking algorithm along with the easterly wave climatology for each atmospheric reanalysis is publicly available from NOAA's National Centers for Environmental Information.

热带西半球东风的气候学

为了了解东风，热带气旋和大型环境之间的关系，开发了热带西半球东风的稳健气候学。气候学的基础是一种新的东风波跟踪算法，该算法可以识别热带东太平洋，大西洋和非洲向西传播的干扰。为了评估航迹依存关系和东风海浪表示的问题，应与NCEP-NCAR，CFS-R，ERA-40和ERA-Interim重新分析分开准备气候。每次大气再分析的东风波跟踪算法的源代码和东风气候，都可以从NOAA国家环境信息中心公开获得。
