<p style=";text-align:left;direction:ltr"><strong>Arab Weather website -</strong> Dr. Jamal Al Musa</p><p style=";text-align:left;direction:ltr"> <strong>1- The amount of water vapor in the air:</strong> Since the density of water vapor is less than the density of air, when the amount of water vapor in the air of an area increases, it displaces part of the air from that area to replace it, so the value of the atmospheric pressure decreases, and the opposite occurs when the amount of vapor decreases Water in the air of an area.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> So, the proportion is inverse, meaning that the amount of water vapor in the air is inversely proportional to the atmospheric pressure.</p><p style=";text-align:left;direction:ltr"><br /><br /> <strong>2- Temperature:</strong> The amount of atmospheric pressure decreases with the increase in temperature, because the air when heated expands, which leads to a part of it moving to the other side and this leads to a decrease in the weight of the air column and a decrease in its pressure. Whereas, when the temperature drops, the air shrinks and shrinks in size, and new air is added to it, which increases its weight and thus increases its pressure. The proportion here is also inverse.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> That is, the amount of atmospheric pressure is inversely proportional to the temperature.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <strong>Read also:</strong></p><p style=";text-align:left;direction:ltr"> <strong><a href="https://www.arabiaweather.com/ar/question/%D9%85%D8%A7-%D8%A7%D9%84%D8%B... are the factors affecting atmospheric pressure?</a></strong></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <strong><a href="https://www.arabiaweather.com/ar/content/%D9%85%D8%A7%D9%87%D9%88-%D8%A7... is atmospheric pressure?</a></strong></p><p style=";text-align:left;direction:ltr"></p>
