Climatology higher latitudes. Models can range from relatively simple to quite complex: In contrast to meteorology, which focuses on short term weather systems lasting up to a few weeks, climatology studies the frequency and trends of those systems. It studies the periodicity of weather events over years to millennia, as well as changes in long-term average weather patterns, in relation to atmospheric conditions. study both the nature of climates – local, regional or global – and the natural or human-induced factors that cause climates to change. Climatology considers the past and can help predict future climate change. Phenomena of climatological interest
Weather reconnaissance radar and satellite data and only provides information that is useful for short-term (up to four hours before launch or landing) but not long-term forecasting. Aerial reconnaissance often provides a more accurate assessment of weather conditions than radar or satellite imagery. Weather reconnaissance is also provided by weather balloons. Weather reconnaissance Weather reconnaissance is the acquisition of weather data used for research and planning. Typically the term reconnaissance refers to observing weather from the air, as opposed to the ground (for example, ground-based weather radar). Helicopters are not built to withstand the severe turbulence encountered in hurricane rainbands and eye
