Effective Assimilation of Global Precipitation: Simulation Experiments
Past attempts to assimilate precipitation by nudging or variational methods have succeeded 1 in forcing the model precipitation to be close to the observed values. However, the model 2 forecasts tend to lose their additional skill after few forecast hours. In this study, a local 3 ensemble transform Kalman filter (LETKF) is used to effectively assimilate precipitation by 4 allowing ensemble mem...

متن کاملGlobal warming without global mean precipitation increase?
Global climate models simulate a robust increase of global mean precipitation of about 1.5 to 2% per kelvin surface warming in response to greenhouse gas (GHG) forcing. Here, it is shown that the sensitivity to aerosol cooling is robust as well, albeit roughly twice as large. This larger sensitivity is consistent with energy budget arguments. At the same time, it is still considerably lower tha...

This is a preliminary PDF of the author-produced manuscript that has been peer-reviewed and accepted for publication. Since it is being posted so soon after acceptance, it has not yet been copyedited, formatted, or processed by AMS Publications. This preliminary version of the manuscript may be downloaded, distributed, and cited, but please be aware that there will be visual differences and pos...
