Quick answer
What does “gradient wind” mean?
A theoretical wind that blows parallel to curved isobars, balancing the pressure gradient force, the Coriolis force, and, for circular motion, the centrifugal force.

Meaning and Definition
A theoretical wind that blows parallel to curved isobars, balancing the pressure gradient force, the Coriolis force, and, for circular motion, the centrifugal force.
In practical meteorology, it represents a good approximation of actual wind above the friction layer (e.g., in the free atmosphere), especially for large-scale flows like jet streams and trade winds. It is a foundational concept for understanding geostrophic and cyclostrophic wind balances.

Common Mistakes When Using “gradient wind”
- Using 'gradient wind' to refer to any windy slope or a wind that changes speed/方向. Confusing it with 'wind gradient' (shear). Using it in non-technical contexts.
FAQ
Frequently Asked Questions
No. The gradient wind is a theoretical wind for the free atmosphere, above friction. Surface wind is slower and crosses isobars due to friction.
Geostrophic wind assumes straight flow and balances only the pressure gradient and Coriolis forces. Gradient wind accounts for curved flow by also balancing the centrifugal force.
Not directly with a single instrument. It is a calculated or derived quantity based on pressure field analysis, often used to approximate actual upper-level winds from weather maps.
It is a foundational concept for understanding real atmospheric motions above the friction layer, crucial for accurate weather prediction models and aviation safety at high altitudes.
A theoretical wind that blows parallel to curved isobars, balancing the pressure gradient force, the Coriolis force, and, for circular motion, the centrifugal force.
Gradient wind is usually technical/scientific in register.

Learning
Memory Aids
Mnemonic
Think of a car going around a banked curve: the 'gradient' (slope) of the track balances the forces to keep the car on path. Similarly, the gradient wind balances atmospheric forces to flow parallel to curved isobars.
Conceptual Metaphor
BALANCE IS PARALLEL FLOW. The wind is conceptualized as a state of equilibrium between competing physical forces, resulting in a steady, curved path.
