tropical atlantic sst dipole造句

• A strong connection is also found between the tropical Atlantic SST dipole and the overlying atmosphere; enhanced convective patterns and anomalous precipitation appear correlated with warm NH SSTs, whereas the opposite phase is observed across the equator, over the cooler SH waters.
• Other consequences of the Tropical Atlantic SST dipole include modulation of the strength and frequency of the Atlantic hurricanes via a series of mechanisms : a . enhancement of easterly wave propagation during the positive phase of the SST dipole ( associated with a wetter West Saharan Africa and increased convective activity which in retrospect promotes a greater N . Atlantic hurricane activity ), b . influence on moist static stability and vertical wind shear, c . modulation of the North Atlantic Oscillation ( NAO ) by changing the subtropical surface pressure patterns, and thus affecting tropical-extratropical, ocean-atmosphere processes that are vital for the development or the weakening of North Atlantic hurricanes.
