The Accuracy of Weather Prediction Essay -- Meteorology

The purpose of this paper is to condone the put acrosss being made in technology and algorithms in helping advance the accuracy of anticipate. It will contrast the forecasting methods of several decades ago with forecasting methods in use today. In discussing how errors can accumulate over snip and providing simple mathematical formulas as examples, this paper intends to show how the repetition of tike errors can affect the accuracy of weather predictions. IntroductionBack in the days of Thomas Jefferson and George Washington, weather observations were charactered daily but not hourly or by the minute. Such repetition of information didnt seem useful. After the telegraph was invented which enabled information about weather data to be transmitted across the country, they still reported only at once a day. In contrast to todays virtual world of weather, making 24/7 use of climate data from satellites, buoys in the oceans, the ability to record worldwide temperatures, worldwide rainfall records, track wind speeds, pressure pulses of solar wind, carbon dioxide levels, tornadoes and hurricanes...etc (Harris, 2012).An early pioneer of weather forecasting was Vilhelm Bjerknes, and his son Jacob, who described the lifecycle of the extratropical cyclone and divided his ideas for scientific weather forecasting. Bjerknes was disappointed over the unscientific methods of meteorology at the time, which, in contrast was making precise predictions in astronomy and meteorology as he felt, was at a standstill. His goal was to introduce scientific concepts to meteorology. According to Bjerknes, the two main ingredients in weather forecasting was experience of the atmosphere and accurate knowledge of the physical laws that govern it. Bjerknes identified pressu... ...Went treat?.ncep.noaa.gov/nwp50/Presentations. Retrieved February 19, 2012, from www.ncep.noaa.gov/nwp50/PresentationNOAA Earth System investigate Laboratory. (n.d.).
