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
Effects of long-term benzodiazepine use of the literature on use of benzodiazepine and nonbenzodiazepine hypnotics concluded that more research is needed to evaluate the long-term effects of hypnotic drugs. The majority of the problems of benzodiazepines are related to their long-term use rather than their short-term use. There is growing evidence of the harm of long-term use of benzodiazepines, especially at higher doses. In 2007, the Department of Health recommended that individuals on long-term benzodiazepines be monitored at least every 3 months and also recommended against long-term substitution therapy in benzodiazepine drug misusers due to a lack of evidence base for effectiveness and due to
