Global warming without global mean precipitation increase?

Global 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...

How Much Will Precipitation Increase With Global Warming?

during the 1970s made possible the observation of the seasonally shifting patterns of global precipitation. It was not until recently, however, that the record could be considered long enough to investigate longer-term trends and the relationship between global precipitation and global warming. Using data from the Special Sensor Microwave Imager (SSM/I) instrument, Wentz et al. [2007] reported ...

Increase of global monsoon area and precipitation under global warming: A robust signal?

[1] Monsoons, the most energetic tropical climate system, exert a great social and economic impact upon billions of people around the world. The global monsoon precipitation had an increasing trend over the past three decades. Whether or not this increasing trend will continue in the 21st century is investigated, based on simulations of three high-resolution atmospheric general circulation mode...

An Explanation of Global Warming without Supercomputing

A new analytic solution of the radiative transfer equation is proposed. It is an extension of the semi-gray model developed by Weaver and Ramanathan. We consider the two regions of thermal spectra independently. In the …rst the infrared absorption (or radiation) is only due to water vapor. In the second both water vapor and carbon dioxide are active. The pre-industrial values of the correspondi...
