H43E:
Integrated Observations/Modeling of Water Cycle Extremes and Attribution of Changes in the Components of the Hydrological Cycle to Human Influences II Posters


Session ID#: 7834

Session Description:
Anthropogenic influence can alter the magnitude, variability, timing, frequency and other characteristics of the variables which constitute the hydrologic cycle. Analysis of this influence requires accurate observational records as well as climate and hydrologic simulations, and statistical models to separate the anthropogenic signal from internal variability. This session focuses on the improvements in understanding of human influence on the global and regional hydrologic cycle, advancements in the observed and simulated datasets used in attribution studies, and statistical approaches for the detection and attribution of anthropogenic influence. The session emphasizes climate and land use change and how they affect the patterns of precipitation, evapotranspiration, runoff, soil moisture, snow cover, snow water equivalent and their characteristics including timing, frequency, and magnitude. Studies which attribute recent hydroclimatic extreme events, in particular floods and droughts, to anthropogenic signals are strongly encouraged.
