The morning weather map for July 5, shows us the current surface pressure readings. Surface Pressure is very important from a meteorological stand point. We use this to help us identify where our surface pressure centers are just like you see above. Our Low pressure area is over Northeast Colorado and also the High pressure over the Ontario area. Surface pressure is taken hourly from the stations and they are also mostly done on a 24hr basis, however some places will only submit their...
A wetsuit, worn by divers, windsurfers, and others engaged in water sports, is a garment, made of foamed neoprene that provides thermal insulation, abrasion resistance, and buoyancy. The suit provides insulation through bubbles of gas enclosed within the material which reduces its ability to conduct heat. These bubbles also provide buoyancy in water. Contrary to popular belief the layer of warm water trapped between the suit and the skin provides very little thermal insulation. Wetsuits...
A barometer is an instrument that measures atmospheric pressure. The barometer measures pressure exerted by the atmosphere using water, air, or mercury. Through measuring the pressure one can forecast short term weather changes. Evangelista Torricelli is credited with the invention of the barometer in 1643. However, Gasparo Berti unintentionally built a water barometer around the same time. Rene Descartes was also noted as describing an experiment to determine air pressure but there is no...
