Abstract:
This study uses historical records of synoptic observations over northern Eurasia to examine changing frequency of precipitation associated with large synoptic events versus convective and thunderstorm activities. We found days associated with showers and precipitation accompanied by thunderstorms have been increasing in general during the study period of 1966-2000 while the total wet day frequency has been decreasing in all seasons. This study suggests increasing convective and severe weather-related precipitation events may be a significant contributor to higher intensity and more extreme precipitation under a warming climate.
