Pakistan's flood weather eased Atlantic hurricanes http://apocadocs.com/s.pl?1283566213
The stalled weather pattern blamed for disastrous floods in Pakistan and a record heatwave in Russia may have averted disasters elsewhere by putting the North Atlantic hurricane season on hold.
Forecasters had predicted that warm sea-surface temperatures and the onset of the weather pattern known as La Nina would make a busy Atlantic hurricane season this year. In June, Phil Klotzbach and William Gray of Colorado State University predicted 18 tropical storms, with 10 reaching hurricane force and five becoming deadly major hurricanes. The US National Oceanic and Atmospheric Administration forecast similar numbers. Yet this year's hurricane season got off to a very slow start, with only three storms by 20 August, and only one of them, Alex, reaching hurricane strength even briefly. That seemed a fizzle compared with the last busy storm season in 2008, when six of the year's 16 named storms, including major hurricane Bertha, had formed by 20 August.... Klotzbach attributes the calm conditions to dry air subsiding over the oceans, denying tropical storms the moisture that powers their growth. The dry air came from the blocking pattern that stalled the jet stream over Russia and Pakistan, says Judith Curry of the Georgia Institute of Technology in Atlanta. Air rose over Europe and Asia, then descended over the oceans depleted of the atmospheric moisture that fuels hurricanes.
