Document Summary
Weather can be defined as the constant state of the atmosphere. ***weather and climate are not the same, but easily interweaved*** Climate- the collective state of the earth"s atmosphere over a long period of time: long period of time = 30 years, it"s a hot summer does not tell about an area"s climate. You have to look from a standpoint of a long period of time: we have seen warming since the early 2000"s (approximately over the last 15 years) Meteorology- the study of the earth"s atmosphere: weather forecasting: a subset of meteorology. There are days when the forecast isn"t correct. Atmosphere- the gasses that envelope the earth (as well as each individual planet) in the vast area: in weather forecasting, it usually only goes about 10-15 miles into the atmosphere (very shallow) Grg 301k notes: class 1 & class 2. 1870: dept. of war/signal corp: it is against policy to mention the word tornado up until approx.
