The overall description of climate, includes all the information from rainfall, humidity, dryness, cloudy or not, the maximum and the minimum temperature, the speed of the wind, whether the air is gonna be engulfed with dust are there any predictionsof storm or not and if yes what is the direction of the storm. The timings of sunshine and the sunset are also covered in the complete prediction of weather. Giving a weather alert is not a kid's task; it requires loads of research, time and of course dedication.
Keeping in mind the different weather conditions and changing climates, the global climate has been summarized into different zones of global climate, which further helps in the process of prediction of weather.
The main principles on which the climate zones are differentiated are Antarctic and Arctic circles, with 66.5 degrees south and north latitudes. And further the latitudes of Tropic of Cancer and the Tropic of Capricorn at 23.5 degrees north and south respectively. While studying geography you might have heard about the terminology low latitude, and is found between the Tropic of Cancer and Tropic of Capricorn The main characteristics of this area are high humidity, heavy rains and minimal temperature variation and is known as tropical climate.
And middle latitude is the area between the Antarctic and Arctic circles and generally the climate is divided in cold winters and warm summers with a uniformity of rainfall. Now coming to high latitude which lies between the Antarctic and Arctic circles and the poles the part of the globe where the winters are very long and cold while the summers are a little warmer here. And you can often find snowfall in this area.
The climate and weather alerts for the coastal area, mountain region is pretty different from the rest of the latitudes. In some cases the weather predictions fluctuate a lot. So in short the weather alerts depend on the latitude that region fall in.
