Pacific Ocean
planetary air pressure systems and resultant wind
patterns exhibit remarkable uniformity in the south and east; trade
winds and westerly winds are well-developed patterns, modified by
seasonal fluctuations; tropical cyclones (hurricanes) may form south
of Mexico from June to October and affect Mexico and Central
America; continental influences cause climatic uniformity to be much
less pronounced in the eastern and western regions at the same
latitude in the North Pacific Ocean; the western Pacific is
monsoonal - a rainy season occurs during the summer months, when
moisture-laden winds blow from the ocean over the land, and a dry
season during the winter months, when dry winds blow from the Asian
landmass back to the ocean; tropical cyclones (typhoons) may strike
southeast and east Asia from May to December
