Sometimes, it directly affects people's daily lives in terms of movement and feeling cold and hot. Weather manifestations include clouds, rain, snow, winds, hurricanes, cold, heat, humidity and atmospheric pressure.</p><p class="rtejustify" style=";text-align:left;direction:ltr"></p><p class="rtejustify" style=";text-align:left;direction:ltr"> Weather forecasting is one of the most important daily issues in various media sectors. It is updated periodically more than once a day, due to the changes that occur in the weather conditions continuously. Weather forecasting depends on a huge amount of information that is entered into computers for analyzing weather data that are received from thousands of stations around the world that monitor current weather values and elements.</p><p class="rtejustify" style=";text-align:left;direction:ltr"></p><p class="rtejustify" style=";text-align:left;direction:ltr"> Special computers analyze weather data, which are called "supercomputers", and they are few in number around the world. These high-speed devices also produce forecast weather data within global numerical models, based on their maps, weather forecasts are issued for a period of one hour to several weeks. But the accuracy of the weather forecast usually decreases after four days gradually.</p><p class="rtejustify" style=";text-align:left;direction:ltr"></p><p class="rtejustify" style=";text-align:left;direction:ltr"> As for the climate, it is a description of weather phenomena for a long period of time, usually taken for a period of 30 years for a specific region, where the rates of the weather elements are taken for this region in terms of precipitation rates, maximum and minimum temperatures, the prevailing wind pattern, in addition to the percentage of humidity and the percentage of sunlight.</p><p class="rtejustify" style=";text-align:left;direction:ltr"></p><p class="rtejustify" style=";text-align:left;direction:ltr"> According to the climate elements of a particular region, the manifestations and types of vegetation cover, the amount of surface and groundwater are determined, in addition to temperature rates and types of precipitation, such as rain or snow, and thus it is directly reflected in the economic and social lifestyle of this region.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p>
