Learn about the Arab Weather Index to measure the severity of the depressions and the criteria on which this classification depends

<p style=";text-align:left;direction:ltr"><strong>Arab Weather</strong> - Two years ago, Arab Weather Company created an indicator that measures the severity of the depressions and their effects, in order to facilitate the citizens to know the expected effects of the depression, and the classification also helps the concerned authorities in the decision-making process and declaring the state of emergency according to the severity and degree of the air depression and its effects on the atmosphere.</p><p style=";text-align:left;direction:ltr"></p><h2 style=";text-align:left;direction:ltr"><br /> The index is extended to five grades (levels) for each grade of a given rating and severity!</h2><p style=";text-align:left;direction:ltr"><br /> The Arab Weather Index to measure the severity of the depressions extends to five levels or five degrees, which are as follows:</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><br /> 1- <strong>First degree</strong> (weak low): The first class includes low-impact depressions that are associated with small amounts of rain, so that the effects of the first-class depressions in the form of low temperatures and some activity on wind speed and sporadic showers of rain in limited areas.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> 2- The <strong>second degree</strong> (normal low): The second degree includes the usual winter air depressions, it is natural for the Kingdom to be affected by an air depression that brings a clear decrease in temperatures and precipitation in different regions with activity on the speed of the winds and the second-degree atmospheric depressions require the issuance of important recommendations because of their accompaniment Some dangerous weather phenomena.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> 3- The <strong>third degree</strong> (low, medium / high efficiency): The third degree includes atmospheric depressions whose intensity ranges between medium and highly effective, so that the amounts of rain in them are greater and the temperatures are lower and are accompanied by a high abundance of rain, which requires serious alerts because of these depressions are accompanied by more severe weather phenomena From that accompanies the usual depressions.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> 4- The <strong>fourth degree</strong> (low and highly effective): The fourth degree includes highly effective atmospheric depressions, which are associated with effects closer to the effects of the storm, bringing strong winds and more intense rains.
