Researchers Predict Heavier Rainstorms In The Future

A new study by MIT and Caltech researchers has predicted that global warming may lead to heavier rainstorms in the future.

Previous studies have shown that average annual precipitation will increase in both the deep tropics and in temperate zones, but will decrease in the subtropics.

However, it's important to know how the frequency and magnitude of extreme precipitation events will be affected, as these heavy downpours can lead to increased flooding and soil erosion.

It is the frequency of these extreme events that was the subject of this new research.

The research was conducted by Paul O'Gorman, assistant professor in the Department of Earth, Atmospheric and Planetary Sciences at MIT, and Tapio Schneider, professor of environmental science and engineering at Caltech.

Model simulations used in the study suggest that precipitation in extreme events will go up by about 6 percent for every one degree Celsius increase in temperature.

Separate projections published earlier this year by MIT's Joint Program on the Science and Policy of Global Change indicate that without rapid and massive policy changes, there is a median probability of global surface warming of 5.2 degrees Celsius by 2100, with a 90 percent probability range of 3.5 to 7.4 degrees.

Specialists in the field called the new report by O'Gorman and Schneider a significant advance.

According to Richard Allan, a senior research fellow at the Environmental Systems Science Centre at Reading University in Britain, "O'Gorman's analysis is an important step in understanding the physical basis for future increases in the most intense rainfall projected by climate models."

The basic underlying reason for the projected increase in precipitation is that warmer air can hold more water vapor.

So as the climate heats up, "there will be more vapor in the atmosphere, which will lead to an increase in precipitation extremes," O'Gorman said.
