ABSTRACT
Rain is a natural phenomenon. When the water on the earth evaporates, it forms
steam, and then the steam continues to float upward. When it floats and floats to a
certain height, the surrounding temperature will become lower and lower, and then the
steam will become water droplets. When it reaches a certain amount, the phenomenon
of rain will occur. Therefore, it usually rains in summer, because there is a particularly
large amount of water vapor in summer, so the rainfall is particularly large.
Generally, rain is divided into light rain, moderate rain, heavy rain and rainstorm.
The amount of rain in each rain is different. Rain is good for people and bad for people.
It can be said to be a double-edged sword. China is a large agricultural country, and the
growth of crops cannot be separated from rain. Therefore, rain is conducive to the
growth of crops and can irrigate crops. However, if it rains for a long time in rainstorm,
floods will occur, It brings great harm to people's production and life, even endangering
human life.
Therefore, it is very necessary to predict the rainfall, which can prepare for victory
in time and effectively avoid the danger caused by rainstorm.
In the past, people used to predict rainfall in ancient ways, such as watching the
color and density of dark clouds, watching the reactions of animals, such as ants moving
out, swallows flying low, and feeling the speed and size of the wind. In modern times,
people used to watch weather forecasts to observe.
Nowadays, computer technology is developing very rapidly and plays a very
important role in all walks of life. Through computer and network technology, many
things that could not be done before can be achieved, and many new methods have been
invented. Network technology is also widely used in weather. This article focuses on a
very practical rainfall forecasting system, which can accurately predict the rainfall of
each month.
This system uses python technology and time series analysis technology, and the
database uses mysql database, ensuring the powerful system functions and data security.
