论文摘要
冠状病毒SARS-COV-2引起的当前大流行是全球的负面健康，社会和经济后果。在欧洲，大流行在2020年3月底和2020年3月初开始强烈发展。随后在整个大陆上散布，在意大利北部和西班牙内部特殊毒力。在这项研究中，我们表明，在2020年2月的西南欧洲盛行的一种不寻常的持续性反流行局势（即北大西洋和北极振荡的异常强烈的积极阶段）可能会导致有利的条件，而在意大利和西班牙的空气温度和湿度方面，与维尔鲁斯的范围更快地散布了众所周知的欧洲国家。在这些区域中占主导地位的强大大气稳定性和相关的干燥条件似乎是合理的，这可能通过短距离液滴传输以及远距离气溶胶（机载）透射来偏向该病毒的传播。
The current pandemic caused by the coronavirus SARS-CoV-2 is having negative health, social and economic consequences worldwide. In Europe, the pandemic started to develop strongly at the end of February and beginning of March 2020. It has subsequently spread over the continent, with special virulence in northern Italy and inland Spain. In this study we show that an unusual persistent anticyclonic situation prevailing in southwestern Europe during February 2020 (i.e. anomalously strong positive phase of the North Atlantic and Arctic Oscillations) could have resulted in favorable conditions, in terms of air temperature and humidity, in Italy and Spain for a quicker spread of the virus compared with the rest of the European countries. It seems plausible that the strong atmospheric stability and associated dry conditions that dominated in these regions may have favored the virus's propagation, by short-range droplet transmission as well as likely by long-range aerosol (airborne) transmission.
