Árhullám

Árhullám, also known as atmospheric gravity waves, are large-scale waves that propagate through the Earth's atmosphere, typically caused by the displacement of air masses. These waves can be generated by various phenomena, including thunderstorms, volcanic eruptions, and even the movement of air over mountains. Árhullám can travel long distances and can affect weather patterns, causing variations in temperature, pressure, and wind speed.

The waves can be categorized into two main types: gravity waves and Rossby waves. Gravity waves are caused by the force of gravity acting on the displaced air mass, while Rossby waves are caused by the rotation of the Earth. Both types of waves can have significant impacts on weather and climate, influencing phenomena such as jet streams, storm systems, and even the formation of clouds.

Árhullám are studied using a variety of methods, including satellite imagery, radar, and computer models. Researchers use these tools to better understand the behavior of these waves and their role in shaping the Earth's atmosphere. By studying árhullám, scientists can improve weather forecasting and gain insights into the complex dynamics of the atmosphere.
