Why Can You Determine Wind Direction by Wetting Your Finger

question 127

Multiple Choice

Why can you determine wind direction by wetting your finger and holding it up in the air?

• A)Wind carries water molecules, so you can sense the water molecules condensing on the side of your finger that faces the wind.
• B)The wind hitting your finger cools the water down, slowing down evaporation. So the cooler side of your finger is windward.
• C)When a wet finger is held to the wind, evaporation is greatest on the windy side, which feels cool. The cool side of your finger is windward.
• D)Wind direction cannot be determined by wetting your finger because evaporation will occur evenly over the wetted finger.
