Thunderstorm season is spring through summer. What are the merits of a program outside of this window?
There are many benefits. First, like any skill, radar proficiency is not instantaneous—it takes practice. Having a program in the “off-season” provides months of opportunity for practice before the onset of peak thunderstorm season here in the United States. Second, very hazardous weather can occur in the fall/winter so pilots need to be prepared regardless of the month. Last, somewhere in the world, it is always thunderstorm season. Put all this together and it becomes obvious that any time of the year is a good time for our program.
