76 291 2 23/ 73 0.25 How much precipitation did this $100 76 291 2 23/ 73 0.25 How much precipitation did this location receive in the last 6 hours?

$100 0.25 inches Scores

What is the temperature $200 76 291 2 23/ 73 0.25 What is the temperature in Celsius?

$200 76°F = 24°C Scores

$300 35 291 1 23/ * 30 What is the current weather?

$300 * = snow Scores

$400 76 003 2 23/ 73 0.25 What is the barometric pressure?

1000.3 mb $400 [add a decimal between last 2 digits 00.3 then add a 9 or 10 in front answer must be between 950.0 and 1050.0] Scores

76 996 2 23/ 73 0.25 What was the barometric pressure three hours ago? $500 76 996 2 23/ 73 0.25 What was the barometric pressure three hours ago? Scores

997.3 mb $500 The barometric pressure is 999.6 mb currently (996). The barometric trend was +2.3mb over the last three hours. Therefore, the barometric pressure has gone up. Three hours ago the air pressure was lower than it is now. Therefore, subtract the barometric trend from the pressure. 999.6 – 2.3 = 997.3 Scores

$100 The dew point and relative humidity when the dry-bulb is 24°C and the wet-bulb is 9°C.

$100 What is -18°C and 4%? [Find the difference first between the dry-bulb and the wet-bulb (24 – 9 = 15). Then go to column 15 on page 12 of the Earth Science Reference Tables and go down to the row for 24°C.] Scores

$200 The relative humidity when the air temperature is 18°C and the dewpoint is 9°C.

$200 What is 56%? [First go to the Dew Point Chart on page 12 of the Earth Science Reference Tables. Find the air temperature (dry-bulb) row for 18°C, then go across until you find the dewpoint temperature of 9°C (column 5). Stay in column 5 and move down to the Relative Humidity Chart. Go down to the dry-bulb temperature of 18°C and the relative humidity is 56%.] Scores

$300 The wet-bulb temperature when the relative humidity is 100% and the dry-bulb is 40°C.

(If the RH = 100% the wet-bulb and dry-bulb are the same.) $300 What is 40°C? (If the RH = 100% the wet-bulb and dry-bulb are the same.) Scores

Daily Double

This location has the greatest probability of precipitation. $400 This location has the greatest probability of precipitation.

(the temperature and dew point are closest together) $400 What is station 1? (the temperature and dew point are closest together) Scores

The relationship between dew point and air pressure $500 The relationship between dew point and air pressure

$500 What is indirect? (as the air becomes more moist (greater dew point), the air becomes less dense) Scores

The relationship between the ability of the air to hold water $100 The relationship between temperature and the ability of the air to hold water

(warm air can hold more water than cold air) $100 What is direct? (warm air can hold more water than cold air) Scores

The relationship between $200 The relationship between air pressure and air density

What is direct? $200 (more dense air has a greater pressure and sinks (high pressure, high density)) Scores

The relationship between $300 The relationship between altitude and air pressure

$300 What is indirect? (as you increase your altitude (like going up on top of a mountain), the air pressure decreases) Scores

The relationship between $400 The relationship between air pressure and temperature

$400 What is indirect? (as the temperature increases, the air becomes less dense and therefore, a lower pressure) Scores

The relationship between $500 The relationship between relative humidity and temperature

$500 What is indirect? (as long as the actual amount of water in the air stays constant, the relative humidity will decrease as temperature increases) Scores

The three factors that affect the rate of evaporation. $100 The three factors that affect the rate of evaporation.

What are temperature, surface area, and the amount of moisture $100 What are temperature, surface area, and the amount of moisture already in the air? Scores

The instrument used to measure dew point and relative humidity. $200 The instrument used to measure dew point and relative humidity.

$200 What is a psychrometer? Scores

This natural process cleans the atmosphere. $300 This natural process cleans the atmosphere.

$300 What is precipitation? Scores

$400 Evaporation is greatest at this time.

(when the temperature is highest) $400 What is 1pm? (when the temperature is highest) Scores

In order for a cloud to form, warm air must ____ and cool to the ___. $500 In order for a cloud to form, warm air must ____ and cool to the ___.

What is rise and dewpoint? $500 What is rise and dewpoint? Scores

The direction weather systems typically move in the United States. $100 The direction weather systems typically move in the United States.

$100 What is northeast? Scores

$200 This causes the winds.

What are differences in air pressure? $200 What are differences in air pressure? Scores

The wind direction around $300 The wind direction around (a high or low)

(winds are clockwise and away from the center) $300 What is a high? (winds are clockwise and away from the center) Scores

$400 A high or low pressure.

(this is a hurricane (cyclone)---an area of intense low pressure) $400 What is a low? (this is a hurricane (cyclone)---an area of intense low pressure) Scores

$200 Air Rising or Sinking

(air always rises in a low pressure area) $200 What is rising? (air always rises in a low pressure area) Scores

$300 Land or Sea Breeze?

$300 What is a land breeze? (The high would be located over the land (air sinking). Winds always blow from high to low (from land to sea in this picture). Winds are named for the direction from where they come.) Scores
