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

观察到的北极增湿趋势被认为是北极迅速变暖的重要驱动因素。北极的水分主要来自较低纬度，因此了解水分输送过程中的转化机制及其在气候变暖中的变化是很重要的。由于蒸发和冷凝等水文过程依赖于质量，水同位素可作为气团历史的综合示踪剂，提供有关运输事件的补充信息，有助于改进模型描述和预测。

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.
