Unit 6 Topic 1 Relative Humidity / Dew Point / Winds

Which weather variables are most easily determined by using this weather instrument?

• relative humidity and dew point

• air pressure and cloud type

• visibility and wind direction

• air temperature and windspeed

Base your answer to the question on the ESRT, the diagram and your knowledge of Earth Science. The diagram shows a section of the shore of Lake Ontario. Surface air-pressure readings are shown for three of the locations. When converted to inches of mercury, the air pressure reading of 1,017 millibars at C is equal to (refer to the ESRT).

• 30.03 in

• 30.00 in

• 30.30 in

• 33.0 in
