Question

A forecaster may say that he or she looks for "right-moving" thunderstorms when predicting severe weather. the "right-moving" thunderstorms move _____.

Answer 1

Here is the answer to the given question above. The majority of supercell thunderstorms move to the right of the mean layer wind. This tendency is the result of differences in barometric pressure that develop as vertical wind shear interacts with the storm's updraft. In response to this vertical wind shear, an area of low pressure develops in the upper region of the down shear (right) side of the storm's updraft. In contrast, a region of relatively higher pressure forms on the other side of the updraft in the up shear portion of the storm. The region of low pressure on the right side of the updraft creates a favorable environment for propagation of the storm and, in response, it moves to the right.
