MILWAUKEE - The weather word this week is cold and dry, but now add windy to the forecast for today, tonight and tomorrow in the Milwaukee area.
The wind is courtesy of once hurricane and now post tropical storm Sandy which has a wind field that extends for hundreds of miles.
There should be plenty of sunshine but the winds will be from the north-northwest at 15 to 30 miles per hour with gusts to forty miles per hour. Super Storm Hurricane Sandy on Monday evening was downgraded to a post tropical storm by the National Hurricane Center.
Tropical storm systems and low pressure systems are all part of the family of cyclones in meteorology.
Low pressure systems that we experience all year long as snow storms and severe weather makers are called extra-tropical cyclones, while hurricanes and tropical storms are in the family of tropical cyclones.
A cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth. They are characterized by inward spiraling winds that rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
Tropical cyclones are circular, closed systems fed by constant heat from warm oceans, while extra tropical cyclones are fed by cold air on one side meeting warm, humid air on the other side, a more comma shape.
