Gust and Lull
The rhythmic rise and fall of wind speed, a cycle shooters use by timing their shots to a repeatable lull or a steady condition.
Wind rarely blows at one constant speed; it pulses between gusts and lulls in a cycle that often repeats over a span of seconds. A gust is a brief surge above the average and a lull is the calmer trough between surges, and watching that rhythm tells a shooter how much the condition is actually varying. Reading the cycle is central to wind reading, because the spread between gust and lull defines how much error an unlucky shot can carry.
The practical move is to pick a condition you can recognize and hold for it, usually a repeatable lull, then break the shot when the wind returns to that value. This lets you commit to one wind value instead of chasing every change, and it pairs naturally with a wind bracket that captures the high and low you might see. Watching mirage boil and flatten gives a sensitive cue to where you are in the gust and lull cycle.
