  6. 6. Comparison chartClimate WeatherDefinition:Describes the average conditions expected at a specificplace at a given time.A regions climate is generated by theclimate system, which has five components: atmosphere,hydrosphere, cryosphere, land surface, and biosphere.[1]Describes the atmospheric conditions at a specificplace at a specific point in time. Weather generallyrefers to day-to-day temperature and precipitationactivityComponents:Climate may include precipitation, temperature, humidity,sunshine, wind velocity, phenomena such as fog, frost, andhail storms over a long period of time.Weather includes sunshine, rain, cloud cover, winds,hail, snow, sleet, freezing rain, flooding, blizzards,ice storms, thunderstorms, steady rains from a coldfront or warm front, excessive heat, heat waves andmoreForecast: By aggregates of weather statistics over periods of 30 yearsBy collecting meteorological data, like airtemperature, pressure, humidity, solar radiation,wind speeds and direction etc.Determined by:Aggregating weather statistics over periods of 30 years("climate normals").Real-time measurements of atmospheric pressure,temperature, wind speed and direction, humidity,precipitation, cloud cover, and other variablesAbout:Climate is defined as statistical weather information thatdescribes the variation of weather at a given place for aspecified interval.Weather is the day-to-day state of the atmosphere,and its short-term (minutes to weeks) variationTime frame: Measured over a long period Measured for short termStudy: Climatology Meteorology6
