Weather and Climate

by Lauren Olivares

​Climate vs. Weather

• ​Climate- the average weather condition of a given area over a long period of time.

• ​Climate does not change from day to day.

• ​Examples of Climate

  • ​average tempurature (seasons)

  • ​average rainfall

  • ​average temperature of a region

• ​Weather- condition of the atmosphere on a certain day at a certain time.

• ​Weather can change from day to day.

• ​Examples of Weather

  • ​rainy

  • ​sunny

  • ​windy

  • ​snow

​Weather Measuring Tools

​Thermometer

​Used to measure temperature.

​

• Temperature is measured in Fahrenheit or Celsius.

• Low Temperature = Cold Weather

• High Temperature = Hot weathe

​Rain Gauge

​

A tool that is used to measure the amount of rain that has fallen.

​

• It looks like a transparent cylinder with markings.

​Weather Vane/Sock

​A tool that tells the direction of the wind.

• Wind direction is measured in N, NE, E, SE, S, SW, W, or NW.

• A "wind sock" can be used to measure wind direction also, but it does not have the directions marked on it.

​Anemometer

​A weather tool that measures wind speed.

• As wind speed increases, the cups will spin faster and the speed of the wind will be read digitally.

• Wind speed is measured in "miles per hour" (mph).

​Barometer

​A tool for measuring atmospheric pressure or air pressure.

• Atmospheric pressure, or air pressure, is the weight of the air.

  Higher pressure = clear, dry, and sunny skies (This has NOTHING to do with temperature!)

  Lower pressure = cloudy skies with a chance of precipitation

​Hygrometer

​A tool for measuring humidity of amount of water vapor in the air.
