Measurement of cloud cover

Question

We want to measure the potential rainfall of the area. For this can we measure the cloud cover and what is the relation between cloud cover and precipitation?

cloud cover
 
Sky conditions are estimated in terms of how many eighths of the sky are covered in cloud, ranging from 0 oktas (completely clear sky) through to 8 oktas (completely cover). Cloud cover is estimated in Oktas by metrological people. But the rainfall depends in may of the other factors. As we know, Different areas of the Earth’s surface receive different amounts of precipitation. Latitude: it rain more in the areas near the equator than in the temperature zones and polar regions. The temperature is higher near the Equator so there is more evaporation. Altitude: it rains more in high areas than in low areas.Level of humidity: it rains more on the coast than inland. Seas are a source of humidity. Also rainfall at a place is dependent on wind velocity, temp etc.
We can not estimate the rainfall depending on the cloud cover. There is a corelation for every cover and as I said the area. You can contact the metrological stations of your area and understand the relation between the clouds and the rainfall. Once you get this you can then estimate potential rainfall. Cheers:::
