Meteorologists will typically use soundings (skew-T charts) and hodographs to spot LLWS conditions, along with radar velocity wind profiles and mesoscale models.

The layout of the current conductors and the points at which the hodographs of the MF will be considered are shown in Fig.
Figure 2 illustrates the three-block failure mechanism and velocity hodographs. Based on the normality rule, the direction of the velocities inclines with an angle [phi] with discontinuous surfaces, where [phi] is the friction angle of the soil in which the discontinuity surface lies.
Thus armed, he explains the average and extremum values of variables, the central force problem, vector hodographs in planetary motion, planetary motion in Cartesian coordinates, the planetary problem in complex coordinates, Keplerian motion in the solar system, and planetary motion in three-dimensional space.
At the time, it was expected that the main threat would be straight line winds, but low level hodographs were strong, with storm-relative helicity values of 300-400 J/Kg and upper air soundings with 0-6km shear at 50-60 kts.
Afterglows such as Diamond Ring are virtually instantaneous hodographs - a display of wind direction and velocity.
Hodographs of vectors of magnetic flux density: a) the original, created by power lines; b) compensation windings; c) the total generated by the power lines and the system enabled
At this time, the left member from the storm split is much weaker and less organized, consistent with previous numerical studies that showed enhancement of the right mover in environments with hodographs turning clockwise with height (Klemp and Wilhelmson 1978b), as is the case here.
Stability conditions stated in terms of hodographs (frequency plots) have a long history.
I regularly work with hodographs, plots of wind vectors with height, and we see all sorts of shapes, especially in the 0-1 km layer which is critical to tornado forecasting.
The velocity hodographs are shown in Figure 3, in which [v.sub.b] is the velocity of rigid block b; [v.sub.ah] is the velocity at the end point N of the log-spiral shear zone a; [v.sub.c0] is the velocity at the start point M of the log-spiral shear zone c.
