A type of brush map which adds a jet stream to a celestialBody.

To add a jetStreamMap, one needs an upper brush map, a surface brush map, and a transition curve. This map can be combined with a Noise function.

jetStreamMap

These maps are set at the upper limit of the atmosphere and at sea level. They can be combined with noise functions.

Velocity Brush

The value of the brush determines strength and direction, with white being maximum east, grey being 0, and black being maximum west.

Parameters

streamMaxVelocity: a scalar which determines the maximum velocity a jet stream may travel, expressed in m/s.
headingTurbulence: a scalar which determines how much the wind direction may vary.
velocityTurbulence: a scalar which determines how much the wind speed may vary.
timeTurbulence: a scalar which determines how quickly the wind may fluctuate.

transitionCurve

A curve which determines the strength of each map at given altitudes. This is identical to the curve editor used to modify the shape of the noseCone mesh or the Wing dragCoefficient.

For example, a straight line represents a linear transition. Alternatively, an exponential curve represents one map quickly transitioning to another.
