GEOSTROPHIC WINDS Meaning and
Definition
-
Geostrophic winds refer to the horizontal movement of air in the atmosphere that occurs when the pressure gradient force is balanced by the Coriolis force. This term is commonly used in meteorology and describes a type of wind flow which is predominantly parallel to isobars (lines of equal pressure) on a weather map.
In more technical terms, geostrophic winds are primarily caused by the imbalance of pressure between two different regions. Air moves from areas of higher pressure to lower pressure, creating a pressure gradient force. However, the rotation of the Earth generates the Coriolis force, which deflects the moving air to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Consequently, the pressure gradient force and the Coriolis force balance each other, resulting in a circular pattern of air movement around areas of high and low pressure.
Geostrophic winds are characterized by their steady and uniform flow, typically at higher altitudes in the atmosphere. They are not influenced by surface friction and are thus more prevalent in the free atmosphere. Geostrophic winds play a significant role in shaping weather patterns, as they contribute to the formation of high and low-pressure systems and influence the movement of weather systems.
Understanding geostrophic winds is crucial for meteorologists, as they provide valuable insights into atmospheric dynamics and can help forecasters predict weather patterns and make more accurate weather forecasts.

Etymology of GEOSTROPHIC WINDS
The word "geostrophic" is derived from the combination of two Greek words: "geo" meaning "Earth" and "strophē" meaning "turning". The term "geostrophic winds" was coined to describe a type of wind flow that occurs when the Coriolis force and pressure gradient force are in balance. These winds move parallel to isobars (lines of equal pressure) at a constant speed and direction, resulting in a balance between the pressure gradient and Coriolis forces. Hence, "geostrophic winds" refers to the Earth's turning winds that result from this balance.
