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
Systematics – study of multi-term systems available to make such distinctions. Beyond the 12-term system he spoke of "societies". Bennett correlates the logical levels or leaps of qualitative complexity with what he calls the "concrete" or "qualitative" significance of number, perhaps again analogous to what Russell calls "relation number" in "Principia Mathematica" and in looser reference to Pythagorean traditions, although Bennett was at pains to distinguish what he was doing from various kinds of mere "numerology". The series of Bennettian systems includes the monad, dyad, triad, tetrad, and so on, open-endedly. Systems progress in complexity from the monad up, and from vague wholeness to increasingly articulate
