- Downbursts.
- Microbursts.
- Gust fronts.
- Straight-line winds.
- Derechos.
Why do boats use knots instead of mph?
In modern times, a knot is a unit of speed that ties directly into the global latitude and longitude coordinate system. Therefore, in the aviation and nautical worlds, knots are oftentimes used in place of MPH and KPH since they are easier to navigate with.

9. Strong/severe gale. 41–47 knots. 47–54 mph. 75–88 km/h.
