Document Summary
Climate: main difference is a measure of time, climate is what you expect, weather is what you get, ex. Expect summers to be warm, winters to be cold: climate change refers to changes in long-term averages of daily weather. Weather: the sum total of atmospheric conditions at specific, concise time, momentary state of the atmosphere, minutes, hours, days, temperature, precipitation, atmospheric pressure, winds, humidity. If our jet stream is below us, then temperatures are likely to be warmer than average. Highs and lows: pressure change: weather is affected by up and down movements of masses of air with high and low atmospheric pressure, affect daily weather, measured using barometers. Form over warm ocean waters and sometimes pass over costal land: atlantic ocean are called hurricanes, pacific ocean are called typhoons, 400-1600 km in size. Hurricane irma: most powerful storm ever recorded in the atlantic ocean, most powerful winds (298 km/h) for longest period of time (37 hours)
