According to Environment Canada, what was the top weather story of 2011?
|
Major floods that happened in the prairies, mostly due to dams
|
|
What climate-change processes might you expect to witness during your lifetime? Which ones do you think take too long for you to experience?
|
We can experience seasons, and also El-Nino. However we cannot experience global warming or an ice age in our lifetime.
|
|
The thermosphere has extremely high temperature, but a person exposed to it would rapidly freeze. Explain this apparent contradiction.
|
The gas molecules in the thermosphere are very spread out, and so there is very little contact. This means that heat is poorly conducted in that environment.
|
|
Does the equivalent of Northern Lights occur in southern hemisphere?
|
Yes, Aurora Australis, the Southern lights.
|
|
Pressurized cans of shaving cream advise users not to expose the product to excessive heat? What might happen if the advice is not followed? Will this potential problem remain throughout the life of the product?
|
Once the cans are exposed to heat soon after purchase, there will be a big explosion, however soon after, the pressure in the can will decrease and therefore the explosion wont be as dangerous
|
|
A standard pressure of 1013.2 mb is also known as 1 atmosphere (ATM). Look at the next figure and determine at approximately what levels you would record a pressure of 0.5 ATM and 0.1 ATM
|
0.5 ATM = 500 mb
0.1 ATM = 100 mb |
|
Would you expect both the Northern and Southern hemispheres to have the same average albedo? What factors might cause the two hemispheres to reflect different percentages of insolation back to space?
|
No, the Southern hemisphere has more water (ocean) and therefore less land. On the other hand, the Northern hemisphere has more land, and thus when it snows, it can reflect more Albedo
|
|
Which would have the greatest e ffect on the Earth's greenhouse e ffect: removing all of the CO2 from the atmosphere or removing all of the water vapour? Explain why you chose your answer.
|
There is more water vapor in the air, however the CO2 has the ability to trap and reflect more infrared radiation back. Removing either, would have quantity wise, the same impact
|
|
Suppose that the Earths axis were tilted at 40 to the plane of the ecliptic, instead of 23.5. How would the seasons change in Hamilton? What would be the global eff ect of the change?
|
Summer would be more hotter and winters would be more colder. Globally, there would more pronounced differences in the hemispheres
|
|
An orchard farmer hears a weather forecast for overnight low temperatures to hover just above freezing point of 0C, but with wind chill temperatures expected to drop signi cantly lower. Will the wind chill increase the possibility of frost damage? Why or why not?
|
There is a potential for the soil to lose its moisture and become more dried up, however the plant does not have a nervous system and so does not sense the same feelings as we do. Furthermore, there is a layer of moisture surrounding the plant
|
|
How can frozen clothes "dry" outside in subfreezing weather? What is taking place?
|
The ice in the clothes sublimates and turns into gas, a very slow process that takes place
|
|
A crowded classroom is fi lled with students. In what way does the presence of the students aff ect the dew point and relative humidity in the room?
|
More people means a high temperature and more moisture. The temperature increase leads to a higher Dew points and Relative humidity depends on moisture content, so it would also increase
|
|
What time of year will unstable conditions be most common over the continental United States and Canada?
|
Summer because the ELR will be greater than the DALR and MALR due to warmer ground in the summer time
|
|
Is the stability of the air more likely to change rapidly near the surface or aloft? At what time of day are major changes in the ELR most likely?
|
At noon when the sun is at its highest and the most Insolation is received. It will happen more likely near the surface
|
|
Why are advection fogs rare over tropical water?
|
Very warm water in tropical areas so moist warm air flows over warm water, no contrasting temperatures, and so no condensation
