Fronts Meteorologists use station models to record and describe weather conditions. Convection transfers heat through the exchange of hot and cold molecules. May 21, 2019 Unit 6: Meteorology

Station Model Each station model is marked by a circle and symbols. May 21, 2019 Unit 6: Meteorology

Cloud Cover Cloud cover is represented in this circle. It represents approximately 75% cover. May 21, 2019 Unit 6: Meteorology

Wind Direction Winds are named for the direction they come from. It is shown here. May 21, 2019 Unit 6: Meteorology

The marks here are called feathers. Wind Speed The marks here are called feathers. A long feather means a wind speed of 10 knots. A short feather means a wind speed of 5 knots. May 21, 2019 Unit 6: Meteorology

Temperature 28 Temperature is in degrees Fahrenheit. Notice no symbol is next to the number. May 21, 2019 Unit 6: Meteorology

28 Visibility Visibility is measured in miles. 1 2 Visibility is measured in miles. It is written as a fraction. May 21, 2019 Unit 6: Meteorology

Weather Conditions 28 * 1 2 27 Dewpoint is in degrees Fahrenheit. Notice no symbol is next to the number. May 21, 2019 Unit 6: Meteorology

* 28 27 .25 Precititation Precipitation is measured in inches. 1 2 27 .25 Precipitation is measured in inches. It is written as a decimal. May 21, 2019 Unit 6: Meteorology

Barometric Trend Pressure is written as a whole number. The plus sign means it’s rising. 28 * +19/ 1 2 27 .25 In the United States, air pressure is measured in millibars. May 21, 2019 Unit 6: Meteorology

* 28 196 +19/ 27 .25 Barometric Pressure If the first number is above 500, put a 9 in front. Put a decimal in front of last number. 28 196 * +19/ 1 2 27 .25 If the first number is below 500, put a 10 in front. Put a decimal in front of last number. May 21, 2019 Unit 6: Meteorology
