Question

nvir nmental Analysis cloud Climatology 3. The map indicates how much moisture is available for The International Satellite Cloud oud Climatolegy Climatology Project (ISCCP) collects | cloud data from weather satellites of precipitation in the lower half of the troposphere. How much precipitable water is available in the far north? several nations to help us understand the role of clouds in climate 4. Notice that precipitable water amounts are high in equatorial regions and decrease poleward, as do temperatures. Why are precipitable water and tem- perature related in this way? Activities Go to http://iscep grss.nasa.goe/productsibros sed2.htm the sccPwebsite. Retain the variable "Total Cloud Amount (%)" and time period-Mean Annual"; then click "View." Go back and select the variable-Mean Precipitable water for 680-310mb"; then click-View. 5. The map indicates how much moisture is available for precipitation in the upper half of the troposphere. Again, precipitable water is most abundant in equato- rial regions. What type of cloud is likely to form there? 1. The map indicates the average annual percentage of cloud-covered sky. What is the range of cloud cover amounts in the far north? In the far south? 2. In general, is cloud cover higher over oceans or land? 6. Recall the patterns of cloud cover (Activity 1) and precipitable water (Activity 3) in the far north. What types of clouds are most likely to form in the far north? It may help to refer to Figure 6-14 What would cause this? Go back and select the variable "Mean Precipitable Water for 1000-680 mb"; then click "View. ISCCP-02 198307-200912 Mean Annual 180 Total U

Explanation / Answer

1. In far north the cloud cover is in between, 55-60 percent, however the cloud cover in far north is lesser than north and is around 45-50 percent

2. In general the cloud cover is higher over the ocean than the land. The availability of water for cloud formation is the reason for higher cloud coverage over ocean than land.
