LAB PRACTICAL for METO 112

1. Station Code: decode this segment from METAR code (3 pts, 1 pt each):

a. Winds 04510G15 means __________________________________ in wind direction and speed?

b. For this Plot, what is the Dewpoint? ___________________

c. Barometric pressure? _____________________

2. Isopleths (3 pts, 1 pt each)

A line of constant pressure is called an ______________________

Lines drawn along a constant wind stream or direction are called

____________________________________

c. Below, you will see three images of a 50 degree F isotherm. Circle the one (a, b, or c) that is done correctly.

3. In the chart below: (4 pts total)

a. How many units are released to the atmosphere by Conduction/Convection? Latent Heat Release? (2 pts, 1 pt each)

___________________________________?

b. For the Radiated from Earth to Space (11 units), notice that the orange arrows detail absorption by the atmosphere, including clouds. In a cloudless sky, why would the radiated to space number be higher? What would that do to a minimum night-time temperature? (2 pts, one each for each question)

4. Stability. (4 pts, one each)

a. If a parcel of air is 30 degrees C and the surrounding air is 27 degrees C, is that parcel unstable at first?

b. If that parcel rises dry adiabatically 500 meters, and the air temperature there is 26 degress C, is it still unstable?

If that parcel is saturated so that it rises those 500 meters moist

adiabatically, is it still unstable?

d. What type of condition is that called?

5. Consider this West to East, up and down slice through a low pressure system with fronts: (4 pts, one each)

The Black Box A is the location of which front?

The Black Box B is which front?

What air mass is in the cold air behind A?

Which location features the greatest upward vertical motion, A or B?

6. Climate (2 pts)

Use the climate chart below and find the two boxes marked A and B. Label their climate using the color legend and coding:
