Question

2. Therefor at mid latitudes (45 degrees), we should be halfway between both these pressure systems. Greenfield (42 degrees North) is close to 45, so as we look south we should see winds coming from the looking to the North winds will be coming from the (NSEW or nwne.sw.se etc). (due to the coriolis effect) and (NSEW or owne.sw.se etc.) 3. These winds will create a boundary meteorologists call a 4. Air masses near this boundary will pick up a spin that is(CW/cCW) 5. Meteorologists call air masses with this spin a (HiLo) pressure system.

Explanation / Answer

Answers:

2. The answer is sw(southwest). This is because if the earth were non-rotating planet, solar heating would cause winds across the mid latitudes to blow in a poleward direction. However, the coriolis effect, which is a result of earth's rotation, causes deflection in the wind towards right in northern hemisphere and left in the southern hemisphere. That is why winds across the northern hemisphere tend to blow from southwest and from northwest in southern hemisphere.

The answer is ne(northeast). This is because the cold air coming from polar high pressure region first flows south and then gets deflected westward due to coriolis effect.

3. The answer is polar front. This is clearly seen on the map of wind belts of the world.

4. The answer is CCW(counter-clockwise). In the northern hemisphere air masses near the polar front pick up cyclonic rotation which is counter-clockwise, which is clockwise near polar front in southern hemisphere.

5. The answer is Lo (low). Near the polar front in each hemisphere there develops polar vortex which is a persistent, low-pressure, large-scale zone that rotates eastward around each pole.
