David and I used Angela's GrADS code page as a major outline. I then had to use David's desk computer to run the code since I don't have my own to do so. I did however make changes to a few of the plots. === ===

=== 2. Calculate zonally averaged P and v over longitude, and plot the resulting latitude-time series. ===

Precipitation seems to peak around June globally.

At 90W, precipitation seems to peak twice. Once around June, and again in September between 30N and the equator.

Meridional wind averaged over longitude seems to peak during summer months, June, July, and August. The max is just south of the Equator.



===3. Average air temperature over both lat and lon, to make a 12-month time series. Which season has the warmest global mean surface temperature? Can you understand why? ===



Since there is so much more land in the Northern Hemisphere compared to the Southern Hemisphere, the average global temperature is the greatest during the Northern Hemisphere summer months. Since land has a lower heat capacity than water, the sun is able to heat it more efficiently during the months it receives the highest amount of incoming SW radiation.

===4. Make a map of the temporal (i.e. seasonal) standard deviation of precipitation, expressed as a percentage of the annual mean precipitation. This might be one definition of a "monsoonal" climate. ===



===5. What is the space-time standard deviation of 'air' (temperature)? ===

The total space-time standard deviation of global temperature I calculated was 15.23 degrees C.
