Regional pressure fluctuations the key to unraveling monsoon mysteries
The first week of August 2010 brought extreme flooding and landslides to many parts of Asia. By August 11, floods in the Indus River basin had become Pakistan’s worst natural disaster to date, leaving more than 1,600 people dead and disrupting the lives of about 14 million people, reported Reuters. Across the border in northeast India, flash floods killed 185 with 400 still missing, reported BBC News.

FRISCO — Hawaii-based scientists say that tracking hemispheric climate patterns can help develop more accurate forecasts for the critical Asian monsoon season, which is critical to the agriculture, economy, and people in the region.
Better monsoon forecasts have been a sort of Holy Grail for meteorologists, but season seasonal predictions of these two types of weather phenomena are still poor. But the research done at the International Pacific Research Center, University of Hawaii at Manoa, shows the strength of the East Asian summer monsoon and storm activity in the western North Pacific depend on fluctuations in the western Pacific Subtropical High, a major atmospheric circulation system in the global subtropics centered over the Philippine Sea.
When this system is strong in summer, then monsoon rainfall tends to be greater than normal over East Asia, and in the western North Pacific there tend to be fewer tropical storms that make landfall. Continue reading

SUMMIT COUNTY — As the Asian monsoon season starts, climate experts are warning that intensifying droughts and floods could threaten food production in key rice-growing areas, posing a threat to hundreds of millions of people across the region.
“Climate change endangers crop and livestock yields and the health of fisheries and forests at the very same time that surging populations worldwide are placing new demands on food production,” Bruce Campbell, who works with an international consortium of agricultural research centers. “These clashing trends challenge us to transform our agriculture systems so they can sustainably deliver the food required to meet our nutritional needs and support economic development, despite rapidly shifting growing conditions.” Continue reading
