õhurõhule

õhurõhk refers to atmospheric pressure, which is the force exerted by the weight of the air above a given point on the Earth's surface. It is a fundamental meteorological variable and is typically measured in units such as hectopascals (hPa) or millibars (mb). õhurõhk is influenced by several factors, including temperature, altitude, and humidity. Warmer air is less dense and exerts less pressure than cooler air, while pressure decreases significantly with increasing altitude due to the reduced amount of air overhead.

Variations in õhurõhk are crucial for understanding and predicting weather patterns. Areas of high õhurõhk are generally associated with stable, fair weather, while areas of low õhurõhk often indicate the presence of clouds, precipitation, and stormy conditions. The horizontal movement of air from areas of high pressure to areas of low pressure creates winds. Meteorologists use õhurõhk data, often displayed on synoptic charts as isobars (lines of equal pressure), to analyze weather systems and forecast future conditions. Changes in õhurõhk can also be felt by individuals, sometimes manifesting as ear discomfort or headaches.
