Q3: Dublin has a significantly low rainfall measure, although it is known as a rainy city, it more than likely won’t last long. I think it stays the same temperature because of its location in Ireland.
Q4: The similarities between the Climographs for Plymouth and Krakow are that they have the most rainfall at the same time of the year, with the highest inch of rainfall beginning in May/June and hitting the highest in July. A difference between the two of them is that Plymouth’s temperature is more equally spread out throughout the year, rather than Krakow’s.
Q5: The precipitation was heaviest as it hit Munich (13 inches) and got lighter as it passed Budapest at around 8 inches. Due to the continental drift there is quite even high temperatures all year round. …show more content…
Q6: The respective climates are so different because the climate in Peru changes altitude very extremely, it goes from freezing cold to extremely hot climates during the year.
There is a major juxtaposition of extremes in Peru. In Huancay, the climate usually remains the same throughout the year. It has a very hot climate and the precipitation levels are quite low, even during the winter months.
Q7: The respective climates are so different even though they are relatively close to each other because Reno is situated right under a mountain range so it is mainly shadowed. San Francisco has more sunshine and a higher temperature as it is not covered by anything.
Q.8: The seasonal rainfall between Nairobi and Quito is quite different as it is more evenly distributed throughout the year in Nairobi. There is more of a drop in the pressure of the weather in Quito and therefore this will lead to more
rainfall.
Tutorial 2: Vertical Air motion in the 3 – Cell General Circulation model.
Hadley Cell:
(A):
31.0 – Dew point temperature for air parcel.
35-31=4 degrees – at 100%
4x10= 400m.
(B)
15km 1
_______
15km = 15,000 = 14,600 = 14.6km. = 7,300 – 7.3 degrees Celsius – 23.7 degrees Celsius. 0.5% per km. 5 degrees Celsius per 1km.
35 degrees Celsius, Relative Humidity = 80%.
(C)
The Dew Point Temperature at which air will have a Relative Humidity of 100%.
RH = Actual vapour pressure _____________________ X 100. Saturation vapour pressure.
RH = 15/20 x 100 = 75%.
RH = 20/20 x 100 = 100%.
Higher temperatures will lower the Relative Humidity.
(D)
15 x 5 = 75 degrees Celsius.
20 – 75 = -55 degrees Celsius.
(E)
(F)
It will rise at the dry rate, then at the moist rate.
Ferrell Cell:
(G)
Starts at 15 degrees Celsius, RH = 80%. Then will rise to 15 degrees Celsius = 100%. (800 degrees Celsius when rises, 8 degrees Celsius when cool).
5 degrees Celsius per 1000m or 0.5 degrees Celsius per 100m.
5000m – 800m = 4200m.
0.5 degrees Celsius x 42 = 21 degrees Celsius.
12 – 21 = -9 degrees Celsius.
(H)
9 less than 100%. Therefore the air will rise at dry air; 5 degrees Celsius per 1000m.
5 x 9 = 45 degrees Celsius.
20 – 45 = -25 degrees Celsius.
(I)
5 x 12 = 60 degrees Celsius.
20 – 60 = -40 degrees Celsius.
Polar Cell:
(J)
The air will rise at dry rate first, then the moist rate, therefore;
If air parcel H has a temperature of -10 and a relative humidity of 80%, the temperature of parcel I will be around 70 degrees Celsius.
Conclusion Questions:
(1)
I think it rises and cools because the humidity affects this process as when air rises it becomes hot and sticky, the higher the humidity the more moisture is in the air. The ratio of the amount of vapour in the air to the maximum amount of water vapour required for saturation.
(2)
The air temperatures near the ground are very high because when air rises it expands and loses heat and when air sinks, it compresses and gains heat. The mechanisms that cool the air temperatures in these regions are rising motion near the equator and quite simply over turning circulation in the subtropics.
(3)
The air pressure is relatively lower at the air parcel C and G, because as air rises it expands and loses heat. Also as the air sinks it compresses and gains heat. The heat at the air parcels F and I will be quite hot. The winds formed at higher altitudes become more continuous. They endure so much longer at this rate and have a higher velocity. They have quite a few advantages over some winds near the ground.
(4)
From relative humidity, it is noted that the ratio of amount of vapour in the air to the maximum amount of water vapour required for saturation.
