Increasing frequencies of warm and humid air masses over the conterminous United States from 1948 to 2005
Time series of individual climate variables, such as air temperature and precipitation, have been thoroughly examined to evaluate climate change, but few studies have evaluated how air masses have varied over time. We use the Spatial Synoptic Classification air mass approach to classify multivariate...
