Learn the basics of meteorology

I came across this excellent video series on youtube made by EIU WeatherCenter. I think the mans name is Cameron Craig and he’s a wonderful teacher. These videos address the very basics of meteorology. After seeing them all, you will have a sound basis to solve almost any  MET questions on the exam.

Several of the 8 questions you must answer in 16 minutes on your exam will be covered here in the videos. After seeing them, you can check your knowledge by doing the questions at the end.

Questions

  1. Where is most of the water vapour in the atmosphere contained?
  • Stratopause.
  • Troposphere.
  • Tropopause.
  • Stratosphere.

2. The layer closest to the earth’s surface where the majority of weather is found is called?

  • Mesosphere.
  • Tropopause.
  • Troposphere.
  • Stratosphere.

3. The pressure of the atmosphere:

  • Decreases at a constant rate as height increases.
  • Decreases at an increasing rate as height increases.
  • Decreases at a constant rate up to the Tropopause and then remains constant.
  • Decreases at a decreasing rate as height increases.

4. Density at the surface will be low when:

  • Pressure is low and temperature is high.
  • Pressure is low and temperature is low.
  • Pressure is high and temperature is low.
  • Pressure is high and temperature is high.

5. Generally as altitude increases:

  • Temperature decreases and density increases.
  • Temperature and pressure increase and density decreases.
  • Temperature decreases and pressure density increases.
  • Temperature, pressure and density decreases.

6. Under what conditions would density be the least at any given place?

  • High altitude, high temperature and high humidity.
  • Low altitude, high temperature and high humidity.
  • Low altitude, low temperature and low humidity.
  • High altitude, high temperature and low humidity.

7. If temperature remains constant with an increase in altitude there is:

  • An inversion.
  • An isothermal layer.
  • Decreased lapse rate.
  • An isohypse.

8. Consider the following statements about air density and select the one which is correct?

  • The effect of change of temperature on the air density is much greater than the effect of change of atmospheric pressure.
  • At any given surface temperature the air density will be greater in anticyclonic conditions than it will be when the mean sea level pressure is lower.
  • Air density decreases with increase of height in the International Standard Atmosphere (ISA).
  • Air density increases with an increase of relative humidity.

Thats all for now guys. Keep on studying.
