Introduction to meteorology questions.

By stating the meaning of all symbols used, write the mathematical formular for each of the following radiation laws:

1. Stefan-Boltzmann law
2. Wien`s displacement law

If the effective temperature at the Sun`s surface is T=5,785 K and the average surface temperature of Earth equal to T=288 K.Calculate the wave length that corresponds to the maximum of emmited radiation from the Earth`s and Sun`s surfaces.

Wind indicates that air flows from high pressure to low pressure areas in the atmosphere. Use any local wind system to show how this happens.

An air mass is a …….. while a front is a ……

1. What is the difference between a thunderstorm and a hurricane?
2. Explain any three cases of severe weather hazards of thunderstorms to aviation industry.

1. The figure indicate a completed pressure analysis of a certain  area of concern. Explain briefly how it is done and name the weather features indicated by letters H and L.

2. Suppose that it is presently warm and raining . A cold front will pass your area in 3 hours. Behind the front it is cold and snowing. Make a persistence forecast for weather that will occur in your area 6hours from now.
