Weather is the condition of the atmosphere over a brief period of time. For example, we speak of today’s weather or the weather this week. Climate represents the composite of day-to-day weather over a longer period of time.
A climatologist attempts to discover and explain the impacts of climate so that society can plan its activities, design its buildings and infrastructure, and anticipate the effects of adverse conditions. Although climate is not weather, it is defined by the same terms, such as temperature, precipitation, wind, and solar radiation.
