WX 201 Exam 2 Questions With Solutions 100% Correct Dew is most likely to form on clear, calm nights Which two clouds can produce precipitation? cumulonimbus and nimbostratus If fog is forming in Denver, Colorado (located on the eastern side of the Rocky Mountains), and the wind is blowing from the east, then the fog is most likely upslope fog On a cold, winter morning, the most likely place for radiation fog to form is in a valley As Apollo 12 ascended into the atmosphere, the height o...

WX 201 Exam 2 questions with solutions 100% correct At what time of day is the relative humidity normally at a minimum? when the air temperature is highest The time of day when the relative humidity reaches a maximum value is usually at the time when the air temperature is lowest. The instrument that measures humidity by measuring the amount of radiant energy absorbed by water vapor is the infrared hygrometer. The relationship between the mass of water vapor in an air parcel and the ...

WX 201 Exam 2 with solutions 100% correct Describe the differences in how we measure snow intensity versus rain intensity? Snowfall intensity is measured by visibility and does not take liquid water content into account (which can be a problem for aviation). Rainfall intensity is measured by rainfall rate (i.e., rainfall amount/hour). For the following situations, discuss which precipitation process (collision-coalescence or Bergeron) would most likely be responsible for: Rain in Nort...
