Document Summary

Mainly the cordillera but does encompass a small section of the interior plains. Spectacular and diverse set of landscapes (mountains, plateaus valleys) There are ten different mountain ranges, the most important being the coastal and rocky mountains. The interior plateau is relatively dry due to orographic precipitation (coastal mountains) Little crop land in this region, majority is found in the interior plains region. Railways were key to attracting bc into canada, they allowed trade to get through the mountains and not have to be shipped through the pacific. Coal, lumber and grain went by rail from the interior of bc and. Prairies to the port of vancouver towards asian market. Moderate temperatures, high rainfall, mild, wet and cloudy winters. Precipitation is around 2,000mm/annum for the coast and less than 400mm/annum in the plateau. A lot of micro climates in this region.

Consider the dry adiabatic rate of DAR=10 Co/1000m, and the moistrate of MAR=6 Co/1000m

1. By how many degrees does air cool if it rises dry adiabaticallyfrom sea level to the top of the coastal range mountains (about 800meters)?
2. If cloudy air rises moist adiabatically 800 meters, how muchwould its temperature change be?
3.Why, specifically, does the temperature change at a differentrate for these two situations?

Chapter 14; Conceptual Question 5:

You are a passenger on a spacecraft. For your survival and comfort,the interior contains air just like that at the surface of theEarth. The craft is coasting through a very empty region of space.That is, a nearly perfect vacuum exists just outside the wall.Suddenly, a meteroid pokes a hole, about the size of a large coin,right through the wall next to your seat.

a) What happens?
b) Is there aything you can or should do about it?

a) From the known value of atmospheric pressure at the surface ofthe Earth, estimate the total number of air molecules in theEarthâs atmosphere. (Hint: Disregard air motion and consider staticequilibrium on the atmosphere. The atmosphere presses on the groundand by Newtonâs 3rd law there is a reaction force acting on theair. What is balancing this force?)

b) During certain seasons, strong winds call Chinooks blow from thewest across the eastern slopes of the Rockies and downhill intoDenver. Although the winds come from mountains where thetemperature is low, the temperature in Denver can climb 20 Â°Cwithin a few minutes after the Chinook wind arrives. Similar windsoccur in the Alps and in Southern California. Explain why thetemperature of the Chinook wind rises as it descends the slopesrapidly? (The answer to this is key to solving the numerical partof the problem, if the air moves very quickly then heat transferinto and out of the air can be neglected in the firstapproximation) Suppose the wind comes from Grays Peak (80 km westof Denver, elevation 4350 m) to Denver (elevation 1630 m) and theatmospheric condition at Grays Peak is -15.0 Â°C and 5.60 x 10^4 Papressure while the conditions in Denver before the wind arrives is2.0 Â°C and 8.12 x 10^4 Pa. By how many degrees C will thetemperature in Denver rise when the Chinook arrives? (Hint: Adetailed discussion of the physics involved in the Chinook windscan be found at http://en.wikipedia.org/wiki/Chinook_wind)
