Questions tagged [climatology]

In contrast to the short-term variable weather, climate describes the mean conditions of atmosphere. Thus it is the statistic of weather (mean values, extrema, etc.). Often a 30-year period is considered. When asking questions about climate, use this tag and also include the [atmosphere] tag.
