By Brian Wallheimer, Purdue University Doppler weather radar will significantly improve forecasting models used to track monsoon systems influencing the monsoon in and around India, according to a research collaboration including Purdue University, the National Center for Atmospheric Research and the Indian Institute of Technology Delhi. Dev Niyogi, a Purdue associate professor of agronomy and earth and atmospheric sciences, said modeling of a monsoon depression track can have a margin of...

A Purdue University scientist has shown man-made changes to the landscape have affected Indian monsoon rains, suggesting that land-use decisions play an important role in climate change. Monsoon rainfall has decreased over the last 50 years in rural areas where irrigation has been used to increase agriculture in northern India, said Dev Niyogi, an associate professor of agronomy and earth and atmospheric sciences. At the same time, heavily urban areas are seeing an increase in heavy...

Researchers say regional surface temperatures can be affected by land use, suggesting that local and regional strategies, such as creating green spaces and buffer zones in and around urban areas, could be a tool in addressing climate change. A study by researchers from Purdue University and the universities of Colorado and Maryland concluded that greener land cover contributes to cooler temperatures, and almost any other change leads to warmer temperatures. The study, published on line and...

Most land-use changes occurring in the continental United States reduce vegetative cover and raise regional surface temperatures, says a new study by scientists at the University of Maryland, Purdue University, and the University of Colorado in Boulder. The study, which will appear in the Royal Meteorological Society's International Journal of Climatology, found that almost any change that makes land cover less "green" contributes to warming. However, a less intuitive finding is that...

If it has already rained, it's going to continue to pour, according to a Purdue University study of how ocean-origin storms behave when they come ashore.More than 30 years of monsoon data from India showed that ground moisture where the storms make landfall is a major indicator of what the storm will do from there. If the ground is wet, the storm is likely to sustain, while dry conditions should calm the storm."Once a storm comes overland, it was unclear whether it would stall, accelerate or...

Purdue University scientists say they've determined tropical storms originating over oceans retain their strength after landfall when ground moisture is high. The study of more than 30 years of monsoon data from India, led by Professor Dev Niyogi, showed tropical storms endure when ground moisture is high, but lose power over dry land. Once a storm comes overland, it was unclear whether it would stall, accelerate or fizzle out, said Niyogi, who also serves as Indiana's state climatologist. We...
