1 Guided Notes Weather Part 1: Weather Factors Temperature Humidity Air Pressure Winds Station Models.
2 1. What is weather? Weather: short-term atmospheric conditions in a specific area at a specific time
3 2. Where does weather occur? Most weather changes occur in the troposphere (atmosphere just above Earth s surface) because this layer contains most of the water vapor.
4
5 3. What are the factors that affect the weather? Temperature, humidity, air pressure, and winds affect the weather. These factors are all interrelated: when one factor changes, one or more of the other factors change.
6 WEATHER FACTOR #1: TEMPERATURE
7 4. How is temperature measured? Temperature: the measurement of the average kinetic energy of a substance.
8 4. How is temperature measured? othermometer: sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol that expands and contracts in the tube with heating and cooling
9 4. How is temperature measured? o There are three major temperature scales used around the world. Most of the world uses Celsius scale, but in the U.S. people still use the Fahrenheit scale. People who work in scientific fields use Celsius or Kelvin scales. See Temperature scale conversions on ESRT page 13
10 .
11 Each line = 2 F Each line = 1 C Each line = 1K.
12 4. How is temperature measured? Practice - Temperature Scales & Conversions: Use the temperature scales on ESRT page 13 to determine the temperatures listed below in Fahrenheit, Celsius, and Kelvin. Room temperature Water freezes Water boils F C K
13 5. How is temperature modeled on maps? Isotherms: isolines that are used to connect equal temperatures
14 5. How is temperature modeled on maps?
15 5. How is temperature modeled on maps? Practice - Drawing Isotherms: The map below is a map of the United States which shows recorded temperatures in degrees Fahrenheit for October 2, On the map below, draw the 30, 40, 50, 60, 70 and 80 F isotherm. Extend the isotherm to the edges of the continent..
16 6. How does temperature affect density? As temperature increases, density decreases. This causes warm air to rise and cold air to sink. Warm air Cold air
17 7. How does altitude affect temperature? Altitude: height above sea level
18 7. How does altitude affect temperature? As altitude increases in the troposphere, temperature decreases because the air gets thinner. (see ESRT page 14)
19 7. How does altitude affect temperature?
20 WEATHER FACTOR #2: HUMIDITY
21 8. What is humidity? Humidity: the amount of water in the air
22 9. How much moisture can the air hold? Moisture capacity: the amount of water that the air could hold o Warm air could hold more moisture than cold air because warm air has more space between the particles: Key = Dry air = Water vapor Cold temperatures Warm temperatures
23 10. How much moisture is in the air? Relative humidity: the amount of water in the air compared to how much water it could hold (expressed as a percentage) o 100% relative humidity means the air is saturated (full of water) and precipitation is likely.
24 11. How can relative humidity be modeled in the classroom? Modeling Humidity: The beakers below represent different air temperatures and the amount of water each air temperature could hold. You have 50 ml of water. Hot 20% Humidity Warm 50% Humidity Cool 100% Humidity Cold 100% Humidity & Precipitation
25 12. How do clouds form? When a parcel of warm air rises, it expands and cools to the dew point temperature to form a cloud. o Dew point temperature: the temperature that air must be cooled to be saturated
26 12. How do clouds form? When air temperature is equal to the dew point temperature: 1) Relative humidity equals 100%, 2) Water vapor will condense (form clouds), 3) Precipitation will occur.
