What causes strong winds under Wind Advisories?

ELMIRA, N.Y. (WETM)- The gradual transition from autumn to winter in the month of November is often associated with more variable weather patterns. Throughout the month, more defined temperature differences provide ideal conditions for blustery conditions. For the second week in a row, a Wind Advisory was issued for most of New York and Pennsylvania, until Nov. 6. Agencies across New York State were also urged to take measures, providing an indication of windy conditions becoming a more common occurrence this time of year. Winds are caused by the movement of air between areas of differing pressure. Uneven heating of the Earth is responsible for contrasts in pressure across the globe. In an area that receives more direct sunlight, the surrounding air becomes warmer than its surroundings. Wa
