摘要这项研究记录了美国东北部两个暖季(5-8月)的对流风暴结构和与强风暴(风、冰雹和龙卷风)相关的环境条件，包括2007年和2002-2006年随机选择的一个暖季。风暴被分为三种主要的对流组织结构(蜂窝状、线性和非线性)以及几个亚类。同样的程序也适用于美国东北部人口稠密的沿海地区，包括新泽西州、康涅狄格州、罗德岛州和纽约。沿海分析包括从2002年到2007年的六个温暖季节。在东北地区，大风事件均匀分布在蜂窝结构、线性结构和非线性结构之间。蜂窝结构是产生冰雹的主要原因，而龙卷风则主要由蜂窝结构和线形结构发展而来。在沿海地区，主要是蜂窝和线性系统产生强风和冰雹，而龙卷风……
AbstractThis study documents the convective storm structures and ambient conditions associated with severe storms (wind, hail, and tornado) over the northeastern United States for two warm seasons (May–August), including 2007 and a warm season comprising randomly selected days from 2002 to 2006. The storms were classified into three main convective organizational structures (cellular, linear, and nonlinear) as well as several subcategories. The same procedure was applied to the highly populated coastal zone of the northeastern United States, including New Jersey, Connecticut, Rhode Island, and New York. The coastal analysis included six warm seasons from 2002 to 2007. Over the Northeast, severe wind events are evenly distributed among the cellular, linear, and nonlinear structures. Cellular structures are the primary hail producers, while tornadoes develop mainly from cellular and linear structures. Over the coastal zone, primarily cellular and linear systems produce severe wind and hail, while tornadoes ...
