GC52B:
Climate Extremes: Patterns, Mechanisms, and Attribution II

Submit an Abstract to this Session



Session ID#: 32444

Session Description:
Although we are seeing more weather and climate extremes, individual events are very diverse, and generalization of trends is difficult. For example, mid-latitude and subtropical climate extremes such as heat waves, droughts and hurricanes have increased, and could have been caused by processes including arctic amplification, jet stream meandering and tropical expansion. This session explores various extreme events and associated changes through diagnostic, modeling and statistical approaches. The session focuses on presentations examining aspects of extreme event prediction, attribution, and mechanisms, as well as on evaluations of model accuracy and potentially controversial theories examining how climate extremes may become stronger or more frequent.
