Understanding winds, jet streams How winds form A graphic and text explain how the air pressure differences start the wind blowing. Another graphic and text explain how the Coriolis effect keeps winds from blowing in a straight line. Different kinds...

A gentle breeze cools the home on a hot summer day. A colorful kite floats high above the heads of a picnicking family at play. The tinkling of chimes beneath a baby's bedroom window lulls the infant to sleep. With sails unfurled, a sailboat races toward the horizon. The wind is friend. A hurricane roars inland, destroying homes and communities. Without warning, a thunderstorm rolls into town, ...

What is Windchill Windchill is strictly a comparison. The baseline for the comparison is conceptually an unclothed individual moving through calm air at about 4 mph (a pretty brisk walking pace!). The comparison works like this: The wind is blowing at 20 mph and the temperature is 20 deg F. If I were out naked, how would this make me feel The answer (from the formula!) is that you'd feel like ...

The Beaufort Scale The Beaufort Scale or Beaufort Wind Force Scale is a system for estimating wind strengths without the use of instruments, based on the effects wind has on the physical environment. The behaviour of smoke, waves, trees, etc., is rated on a 13 point scale of 0 (calm) to 12 (hurricane). The scale was devised in 1805 by the British naval Commander, later Admiral, Sir Francis ...

Teachers' Lab The goal of the Teachers' Lab is to provide teachers and educators with a deeper understanding of commonly taught math and science concepts. Many of the Labs are based upon professional development workshops broadcast on the Annenberg/CPB Channel. Why do windy winter days seem so bitterly cold A winter day with a strong wind can seem much colder than one with only a mild wind, ...

Graphic by: Yiqi Shao The weight of the air above an object exerts a force per unit area upon that object and this force is called pressure. Variations in pressure lead to the development of winds, which in turn influence our daily weather. The purpose of this module is to introduce pressure, how it changes with height and the importance of high and low pressure systems. In addition, this module ...
