[font size=4] DURHAM, NC High-pressure systems over oceans, which largely determine the tracks of tropical cyclones and hydrological extremes in much of the northern hemisphere, are likely to intensify this century, according to a Duke University-led study published online this week in Nature Geoscience.[/font]
[font size=3]The studys findings suggest that as summertime near-surface high-pressure systems over the northern Pacific and Atlantic oceans strengthen, they could play an increasingly important role in shaping regional climate, particularly the occurrence of drought and extreme summer rainfall, in coming years.
Wenhong Li, assistant professor of earth and ocean sciences at Dukes Nicholas School of the Environment, and colleagues used climate model simulations to predict future changes in the strength of the annually occurring North Atlantic Subtropical High, also known as the Bermuda High, and the North Pacific Subtropical High.
According to the simulations, these high-pressure systems will intensify over the 21[small]st[/small] century as a result of increasing greenhouse-gas concentrations. The simulations suggest that an increase in the land-sea thermal contrast the difference between ocean and land heating, as Earths climate warms will fuel the systems intensification.

sun and heat for months and months on end, I might welcome a little more actual WEATHER. You know: fronts moving through, breezes, some clouds on occasion. Perhaps even more rain than the pittance we get (which typically falls all on about 5 total days).

FEMA recently remapped the flood plain, so wed have 100 year floods less frequently
