Question

Please answer all parts and label which number is for what so im not lost.

1. (8pts) Explain why it is necessary for air pressure values to be “corrected to sea level” when plotted on surface weather maps. What is a general relation between pressure differences (in millibars) compared to elevation differences (in meters)?

2. (9pts) Discuss three different types of apparent temperature that we discussed in class. Do not give three examples of the same type of apparent temperature. (Also do not include any types that were not discussed in class [in other words do not just simply give an answer from Google]). For each type, explain why the “how-it-feels” temperature differs from the actual air temperature.

3. (8pts) Draw the atmosphere’s vertical temperature profile from the surface to about 75 miles high. Clearly label the different layers and the boundaries between the layers. (Be sure to properly label the axes of your graph).

4. (9pts) Differentiate between:
a. weather & climate.
b. advection fog & radiation fog.
c. sleet & freezing rain.

5. (6pts) Explain how the following gases affect Earth’s weather and climate:
a. water vapor (H2O):
b. carbon dioxide (CO2):

6. (10pts) (i) Draw a typical 24-hour air temperature variation for:

a. a clear day (solid line)
b. an overcast day (dashed line)
(ii) Specifically highlight the approximate time of maximum air temperature and approximate time of minimum air temperature for the clear day & the overcast day.
(iii) Explain why the maximum and minimum temperatures occur at those times on a clear day (HINT: think radiative balance).

Your graph will display ‘time’ on the x-axis, and ‘air temperature’ on the y-axis.
Assume sunrise at 6 a.m. and sunset at 6 p.m. [local times], and that no weather fronts pass through during the 24-hour time period.

Be sure to draw both the clear day and the overcast day variations on the same graph.

Explanation / Answer

4 a) Weather & Climate.

1. it's the condition of atmosphere over the short period of time.

2. It's the mixture of events that occures in our atmosphere i.e., rainfall, change in temperature etc.

1. It's how the atmosphere behabes over a long period of time.

2. It's an average weather patern in any place.

eg- Climate of Antarctica is different from equitors.

b. Advection fog & Radiation fog

1. It can occur for several days

2. It can cover an large area.

3. Can form in any time of day. some times it can form in the late afternoon or evening hour in the coastal areas.

1. It can occur for less than 24 hrs.

2. It covers small area and they are localized.

3.Can form in the late night or early moring hours.

c. Sleet & Freezing rain.

5. Both the gases i.e., Water Vapur and the Carbon dioxide are the green house gases and they both contribute to the global warming in which water vapour are being generated on the local level by the means of the irregation so it'll definetly will have an localized effect as it in the case of Salah in southern Algeria, where temperature goes upto -3.6 oC. as there is an low amount of water vapour in the atmosphere. where as the Carbon dioxide playes an global role on the scale. It not only impact on any local level where as it can impact on the global scale.
