Climatology Importance. Climatology is important since it helps determine future climate expectations. Through the use of latitude, one can determine the likelihood of snow and hail reaching the surface. You can also be able to identify the thermal energy from the sun that is accessible to a regionWeather forecasts are made by collecting as much data as possible about the current state of the atmosphere (particularly the temperature, humidity and wind) and using understanding of atmospheric processes (through meteorology) to determine how the atmosphere evolves in the future.
The Forecasting Process
Making a weather forecast involves three steps: observation and analysis, extrapolation to find the future state of the atmosphere, and prediction of particular variables. One qualitative extrapolation technique is to assume that weather features will continue to move as they have been moving.The purpose of a weather forecast is to provide as accurate as possible prediction of what the weather will be like in the near future. They are important to most aspects of day to day life, including aviation, boating, other modes of transportation, farming, tourism, sports, etc.
