So far, JSBSim is the only FDM that supports turbulence. Up until now, turbulence was controlled by a single variable setting its magnitude; now, it's controlled by both magnitude and rate. Here are the new properties, replacing /environment/turbulence-norm and its equivalents in the weather config:
/environment/turbulence/magnitude-norm /environment/turbulence/rate-hz The magnitude is a value from 0.0 (none) to 1.0 (severe). JSBSim treats it as a curve rather than a line, so severity increases slowly at the start and then rapidly toward the highest values. This is the highest (or lowest) peak that the turbulence is capable of hitting. The default is 0.0. The rate is the maximum number of times per second that the turbulence can move from neutral to its extreme high or low, or back again.
