Diagnosing moisture sources, transport and transformation with water vapor isotopes from satellites and in atmospheric modeling (E06*)

据信，观测到的北极增湿趋势是北极迅速变暖的一个重要驱动因素。北极地区的水汽主要来自低纬度地区，因此了解水汽输送过程中的转化机制及其在气候变暖中的变化非常重要。由于水文过程，如蒸发和冷凝的质量依赖，水同位素作为一个综合的示踪剂的历史上的一个空气包提供补充信息的运输事件，可以帮助改善模型的描述和预测。

The observed Arctic moistening trend is believed to be an important driver for rapid warming in the Arctic. Moisture in the Arctic is mostly transported from lower latitudes and thus it is important to understand the transformation mechanisms during moisture transport, and its changes in a warming climate. Since hydrological processes such as evaporation and condensation are mass dependent, water isotopes act as an integrated tracer for the history of an air parcel providing complementary information on transport events that can help to improve model descriptions and predictions.
