### So… How’s the Weather?

Weather and Climate, and why they matter

How do we describe weather?
• Temperature-how hot or cool the air is
• Measured in degrees ˚
• Fahrenheit: F (used in the United States)
• Celsius: C (metric system, used in most of the world)
• Every temperature measurement in F or C can be “translated” into the other “language”
• tiempo = weather
• clima = climate
• 1 Mexican peso = 0.0857 US dollars
• 0˚C = 32˚ F (thefreezingtemperature of water
• 100˚ C = 212˚C (theboilingtemperature of water
How do we describe weather?
• Precipitation: How much water falls in a certain area
• Rain: water in liquid form
• measured by a rain gauge in centimeters (metric) or inches
• Snow: water in solid form… measured by a snow gauge
• measured by a rain gauge in centimeters (metric) or inches (U.S. customary system

Q1: How do the ski areas know

how much snow to report?

Q2: Why do some mountains report

different amounts of snow than others nearby?

Q3: After it rains, does it matter how soon you check a rain gauge?

How do we describe weather?
• Wind direction: What direction the wind is going
• Measured by a wind vane
• Wind speed: How fast the wind is going
• Measured by an anemometer
• Humidity: How much water vapor is in the air
• Measured by a hygromoter (or humidity gauge)
• Atmospheric (air) pressure: How heavy air is
• Measured by a barometer
• Why measure these things?
• How do they change the way you feel when you’re outside?
• What else do they affect?
Weather Stations around the world
• The colors show when the stations started being used
Where are our local stations?

The When and Where of weather
• Is there anywhere that doesn’t have weather?
• Weather happens everywhere all the time
• But it’s very different …
• in different places at the same time
• At different times in the same place
• It can be measured
• It can be predicted based on patterns
• but predictions are not always right. Why not?
So What’s Climate?
• Weather: what conditions (like temperature and precipitation) are like at a certain place and time
• “It’s raining in Kansas”
• “Temperatures were below zero last night”
• “The humidity tonight will make it feel even hotter than usual”
• Climate: A pattern over time of what weather is like in a certain area. It includes average temperatures and precipitation, along with extreme temperature and precipitation.
• “The Rocky Mountains get a lot of snow”
• “The tropics have a rainy season and a dry season”
• “Deserts are really dry”
• “The average temperature in July in Denver is 82˚F”
In other words….
• In the words of a scientist:
• Climate is what you expect
• Weather is what you get
• In the words of a middle school student:
• Climate tells you what clothes to buy
• weather tells you what clothes to wear
• Any other analogies? (comparisons)
Climate or Weather?
• If you were planning a party in your backyard, would you want to know about climate or weather?
• If you were Marty, would you want to know about climate or weather?
• If you and your family are going camping for a weekend, what would you want to know about?
• If you were going to another state or country what would you want to know about in order to pack?
What kind of climate….
• Do you like?
• Do you dislike?
• Can you survive in?
• Can’t you survive in?
• What about plants and animals?
