which direction do low and high pressure systems rotate in the northern hemisphere
High-pressure area The direction of wind flow around an atmospheric high-pressure area and a low-pressure area, as seen from above, depends on the hemisphere. High-pressure systems rotate clockwise in the northern Hemisphere; low-pressure systems rotate clockwise in the southern hemisphere.
Northeastern United States The climate of the Northeastern United States varies from northernmost Maine to southernmost Maryland. The climate of the region is created by the position of the general west to east flow of weather in the middle latitudes that much of the USA is controlled by and the position and movement of the subtropical highs. Summers are normally warm in northern areas to hot in southern areas. In summer, the building Bermuda High pumps warm and sultry air toward the Northeast, and frequent (but brief) thundershowers are common on hot summer days. In winter the subtropical high retreats southeastward, and the polar jet stream moves south bringing colder air masses from up in Canada and more frequent storm systems to the region. Winter often brings both rain and snow as well as surges of both warm and cold air. [52]
