Question

(a) In the satellite image of Hurricane 'Andrew' (Figure 2. li). most of the clouds \ isihk* are associated with anticyclonic air (low. Can you explain this apparent paradox?

(b) What is the 'fuel' that drives a tropical cyclone?

QUESTION 2.5 Figure 2.21) is a satellite image of the Earth made ai the same time as the image in Figure 2.1 hut using the electromagnetic wavelengths to which water vapour is opaque. The warmest areas arc black and the coldest while. Thus, dark areas represent regions in which the upper troposphere t^ dry so thai radiation from lower, warmer layers is able to reach the satellite; white areas correspond lo radiation from the upper troposphere, which is cold. B> comparing this image with that in Figure 2.1. use information from this Chapter lo identify the following features;

(1 > cumulonimbus cloud formation in association with ihe ITCZ;

(2) the northern and southern polar fronts;

(3) the subtropical high pressure regions.

Figure 2.20 Satellite image of the Earth, constructed using the 'water vapour' channel (wavelength 6000 nm); the colour is artificial. This image and that in Figure 2.1 show the same view of the Earth and are for 26 March 1982.

QUESTION 2.6 As stated in the caption. Figure 2.3(c) show s surface w inds over ihe Pacific and Atlantic during one particular day in )999. On the basis of what you have read in this Chapter, explain w heiher this was a da> during the northern summer or the southern -ummer. You should be able to cite at least three particular aspects of the wind pattern in support of your answer.

QUESTION 2.7 In Chapter 5, we will be discussing how disturbances may be transmitted from one part of the ocean to another by means of large-scale wave motions. From your reading of Chapter 2. give at least two examples of wave-like atmospheric disturbances.
