简介：响应影响环境条件的活动被付了越来越多的注意到的热带气旋(TC)的变化在最近的年里。单身者和multivariate的潜在的贡献到从1970～2009的年度TC频率和紧张的环境变量在这研究被调查。而不是使用关联系数，那假定一套样品令人满意正常分发，量的大小基于信息理论被提出。结果证明动态环境变量在西方的诺思太平洋，诺思大西洋，和东方太平洋上在TC活动的变化起一个重要作用。这些动态因素包括风在850和200hPa和850-hPa亲戚涡度之间砍。然而，在TC活动的热因素的效果在不同的盆上是不同的。热环境变量仅仅在北方大西洋上在东方太平洋上以及到TC频率有重要贡献到TC频率和紧张。影响TC活动的主要因素是，这被发现确实并非在不同的盆上的一样因为处于越过不同区域的大气的条件和他们的变化的差别。动态变量的效果应该在象热条件总是满足的西方的诺思太平洋那样的区域更被考虑。
