This project will undertake the following: (i) establish the large-scale eastern North Pacific tropical cyclone (TC) climatology and variability, including investigating the near-coastal versus open ocean variability of TC activity and the large-scale circulation patterns associated with the modes of variability; (ii) extend of the current database of near-coastal TC remnants both in time as well as to include 3-dimensional atmospheric information; and (iii) perform the statistical analysis of characteristic circulation patterns associated with particular rain swath patterns across the southwestern U.S. region. The research will increase fundamental understanding of the climate variability of eastern North Pacific tropical cyclones and how a changing climate will alter their impacts on the sensitive southwestern U.S. and Mexico regions. Better understanding of the large-scale circulation patterns that increase TC landfall activity may lead to improved seasonal forecasts of these phenomena as well as resource and management planning into the future.

该项目将开展以下工作：（i）建立大尺度北太平洋东部热带气旋气候学和变率，包括调查热带气旋活动的近岸与公海变率以及与变率模式相关的大尺度环流模式; ㈡在时间和包括三维大气信息方面扩大目前的近海热带气旋残留物数据库;以及（iii）对与横跨美国西南部地区的特定雨带模式相关联的特征环流模式进行统计分析。这项研究将增加对北太平洋东部热带气旋气候变化的基本了解，以及气候变化将如何改变它们对敏感的美国西南部和墨西哥地区的影响。更好地了解增加TC登陆活动的大规模环流模式，可能会导致改善这些现象的季节性预测以及未来的资源和管理规划。
