Perled raw all the data in the station model Temporauro: 74 Dew Point: 72F Precipitation: 0.1 inches Cloud Cover 100% Wind Direction: Southwest Present Weather: Drizzle Wind Spood: 15 knots Air Prossure: 987.4 mb Temperature 91"F Precipitation: 1.5 inches Cod Cover: 100% Wind Direction: North Dew Point 91F Prosent Weather: Thunderstorm Wind Speed: 36 knots Air Proesure: 979.1 mb Torporaturo: 24 Precipitation: 0.3 inches Cloud Cover: 100% Wind Diroction: Northeast Dow Point: 22F Present Weather: Snow Showews Wind Spoed: 10 knots Air Prossure: 989.9 mb Questions and Analysis: 1. 2, Which weather station has the lowest atmospheric pressure? What is the approximate relative humidity for weather station #3? Describe in words the weather conditions at station # 2.

Explanation / Answer

1. second weather station will have lowest atmospheric pressure. since it has the lowest air pressure.

2. Relative humidity for weather station 3:

Relative humidity, RH=100*(EXP((17.625*TD)/(243.04+TD))/EXP((17.625*T)/(243.04+T))), where T is the temperature and D is the dew point.

RH= 91.94 %

3. weather condition at station 2:

Relative humidity= 100%

It has to be 100% relative humidity where the clouds and rain form. There will be a chance for rain and thunderstorm.
