RAINFALL PREDICTION
The paper is about “Rainfall Prediction Using Digital Image Processing”. The main
aim is to use digital cloud image for estimating rainfall and to detect the type of clouds using
different image processing techniques. Water is a life giver - even a life creator. A life without
water is unimaginable. Every single cell in the body requires water in order to function properly.
One important way in which the bodily tissues use water, for instance, is to regulate the body
temperature. Hydraulic power is a wonderful source of green energy, where power is created out
of water. Water is used in agriculture for irrigating fields of crops. A large amount of fresh water
is got from rain. Rainfall is one such important component for life. Rainfall play vital role in our
country’s social and economic development.
Rainfall being that much important, how are they formed as follows. Rain that’s fallen
may have been water in the ocean a couple of days before. The water that is at the top of oceans,
rivers and lakes turns into water vapor in the atmosphere using energy from the sun. The water
vapor rises in the atmosphere and there it cools down and forms tiny water droplets through
something called condensation. These then turn into clouds. When they all combine together,
they grow bigger and are too heavy to stay up there in the air. This is when they will fall to the
ground as rain.
Rainfall can also be predicted with the use of satellite, but it the costliest method. So
digitalimage processing techniques are used to determine rainfall. With a prior prediction of
rainfall, the people can find some way to save the water for future usage. Accurately forecasting
heavy rainfall can allow for warning of floods before rainfall occurs. Additionally, such
information is useful in agriculture to improve irrigation practices and the effectiveness of
applying fertilizer, pesticides, and herbicides to crops. Digitalimage processing is one such useful
technique to predict rainfall.
TECHNOLOGY USED FOR THE RAINFALL PREDICTION
Predicting the rainfall consists of six phases. In the first phase data is collected. In the
second phase the status of sky is found. In the third phase the status of cloud is found. In the
fourth phase the type of cloud is evolved. In the fifth phase the information about the cloud and
the status of rain are displayed. In the sixth phase the analysis and measurement takes place.
