GC41G:
Characterizing and Interpreting Changes in Temperature and Precipitation Extremes I


Session ID#: 10360

Session Description:
Extreme weather events are, by definition, rare, but can have an outsized impact on human society. In this session, we aim to address two related questions with regard to extreme temperature and precipitation events, including drought. First, to what extent have extreme events changed in frequency and/or intensity, relative to changes in the mean? Second, what climatic influences and physical mechanisms underlie variability and changes in extreme events, and how are extremes in temperature and precipitation related? We encourage contributions that utilize new data sources, present novel methods for assessing changes in extremes given limited data, and incorporate observations with physical models.
