The climate predictions are extremely important from many aspects, and some of them are the agriculture, water supplies, and fishing.
The agriculture, in general is heavily dependent on the climate, so being able to make precise prediction about it, will enable the farmers to react in accordance to the circumstances and manage to get as good crops as possible.
The water supplies are heavily linked with the precipitation and the droughts. So by making precise predictions about the climate, the people can properly organize, use, and preserve water throughout the year, in order to have a constant supply of it.
The fishing is dependent on the weather, but also the safety of the fisherman. Making precise prediction about the climate can give green light for safe fishing, or can warn in time the fisherman that it can be dangerous and not wise to fish.
