1. 1.What is the temperature? 2.What is the present weather? 3.What is the wind speed? 4.What is the wind direction? 5.What is the pressure? 6.What is the cloud cover? 7.What is the precipitation? Use the key on ESRT 13 below for help on the Do Now

2. Decoding Barometric Pressure (Copy These Steps Please) Step 1: Put a decimal point before the last digit 196  19.6 Step 2: Put a “9” and a “10” in front of the first digit 1019.6 919.6 Step 3: Pick the number that is in the normal range 1019.6 is in the range Range

3. Decode the these barometric pressures and show the steps!!! 002 280 993 000 #1 #4#3 #2

4. Encoding Barometric Pressure 1013.5 Step 1: Remove the decimal point before the last digit 1013.5  10135 Step 2: Report the last 3 digits 10135  135 Encode these pressures and write the answers in your notebooks: #1 1032.7 #2 987.3 #3 1012.2 #4 1000.1

5. How Barometric Pressure Changes + means “higher than it was 3 hours ago” - means “lower than it was 3 hours ago” 19 means the pressure has change 1.9mb / means pressure is currently rising \ means pressure is currently falling

6. How is the barometric pressure changing for these? -21\ +18/ #1 #2

7. How to determine station wind direction and speed... Calculate wind speed and direction for the following… #1 #2 #3

8. Challenge 1: Fill in the information based on the weather station model Temperature= Dewpoint= Wind Direction= Cloud Cover (%)= Visibility= Present Weather= Pressure Now= Precipitation= Bonus Question Pressure in 6 hours will be…

9. Challenge 2: Create a station model based on the following information Temperature = 45F Dewpoint = 32F Wind = NE at 20 knots Overcast = 100% cloud cover Visibility= 1.5 miles Current Weather= Rain Showers Pressure Now = 997.3 mb Pressure Change = 1.2 mb Barometer Falling Precipitation =.53 in.
