Answers

Based on the readings on the Wet and Dry Bulbs of this weather instrument, the relative humidity is 40%.

What is the relative humidity?

First find the difference between the reading on the wet and dry bulbs:

= Dry bulb temperature - Wet bulb temperature

= 22 - 14

= 8°C

When the difference between these bulbs is 8°C and the temperature on the dry bulb is 22°C, then the relative humidity is 40% as shown in the table attached.

An unsaturated air parcel has a temperature of 25°C at the ground level. The surrounding environmental temperature at the ground level is 24°C. Meanwhile, the dew point temperature is 9°C and the environmental lapse rate is 15°C/1000m. Can the air parcel rise to 2000 meters and form clouds when rising? Why or why not? If yes, at what elevation does the cloud start to form? (DALR = 10°C/1000m, MALR = 6°C/1000m)

Answers

Answer:

See below for what I think is the answer

Explanation:

If the air goes up 2000 ft it will cool by  (given lapse rate 15/1000)

 15 C * 2 = 30 C  

then it will be  25 - 30 = -5C    

so yes it will form clouds as this is below the dew point of 9 C

25 - 15/1000 x  = 9      shows at x = 1067 m to reach dew point and cloud
