Atmospheric sciences and radiant energy. In contrast to meteorology, which studies 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. Climatologists, those who practice climatology, 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 include the atmospheric boundary
Systematics – study of multi-term systems the problem of understanding ourselves and the world." He notes in this general context 4 branches of Systematics: Bennett's use of the term "Systematics" is basically synonymous with what today falls under the terms "systemics", "systemology", "systems science", and "systems theory". However, his own specific work under the name "Systematics" takes approaches that are still unfamiliar to many current systems specialists, making his work a specialty in a much broader field. In addition, the use of the term "systematics" in biology to refer to the classification of types and forms of organisms creates ambiguity and rather overwhelms the term's current
