Steering Level For Cyclones guided by winds near 700 mb
Surface systems often follow the prevailing airflow at this level.
Steering flow A basic fluid flow which exerts a strong influence upon the direction of movement of disturbances embedded in it. This is usual concept of steering in meteorology.
Steering - Directing other motion. The jet stream steers surface storm systems.
Subsidence - Sinking air.
Supercooled water - Water that is below the freezing temperature but is still in liquid form.
steering - In meteorology, loosely used for any influence upon the direction of movement of an atmospheric disturbance exerted by another aspect of the state of the atmosphere.
Steering winds
Although tropical cyclones are large systems generating enormous energy, their movements over the Earth's surface are controlled by large-scale winds-the streams in the Earth's atmosphere.
Steering Winds (or Steering Currents) - A prevailing synoptic scale flow which governs the movement of smaller features embedded within it.
Steering Currents
Same as Steering Winds; a prevailing synoptic scale flow which governs the movement of smaller features embedded within it.

STEERING CURRENT - A flow of air that determines the track of a weather disturbance or storm embedded in it. Commonly applied to tracks of tropical cyclones. May also be called STEERING WINDS.
Left MoverA thunderstorm which moves to the left relative to the steering winds and to other nearby thunderstorms; often the northern part of a splitting storm.
The positive phase brings the opposite conditions, steering ocean storms farther north and bringing wetter weather to Alaska, Scotland and Scandinavia and drier conditions to areas such as California, Spain and the Middle East.
The northern polar jet stream associated with the polar front is a steering mechanism in the atmosphere.
A thunderstorm that moves appreciably to the left relative to the main steering winds and to other nearby thunderstorms. Left movers typically are associated with a high potential for severe weather.
The method employed for electronic beam steering in phased-array radar. 3.
Average wind over a deep layer of the atmosphere, giving a representative steering wind.
*Right Mover - A thunderstorm that moves appreciably to the right relative to the main steering winds and to other nearby thunderstorms. Right movers typically are associated with a high potential for severe weather.
