To define a “directional storm” pertaining to a certain sector (ϑ i ± δ ϑ) the variability of wave direction during the storm has to be investigated. The analysis proposed in this paper (see next section) shows this variability; it is quite high in storm tails (lower sea states), but lower near storm peak (when stronger sea states occur).

[1] a comprehensive directional wave buoy data set showing the directional wave spectrum during the passage of a number of hurricanes is presented. The data confirm remote sensing measurements, showing that waves in the forward quadrants of the storm are dominated by swell radiating out from the intense wind regions to the right of the storm centre.
Wave systems are born out of the influence of winds, both local and distant, and evolve on the sea surface. Waves which propagate without regard to the local winds (because either the phase speed is faster than the wind or the direction of propagation perpendicular to the wind) are traditionally known as swell.

The maximum entropy method (mem) of directional wave analysis paired with a single-wave probe/ bi-directional current meter sensor is found to be the most satisfactory method to measure multidirectional seas in a wave basin over a wide range of wave conditions.
The directional spreading of sea states is an important design parameter in offshore engineering. Wave directionality affects the resulting wave kinematics, which affects the forces exerted on offshore structures.

Directional shear in the lower troposphere helps initiate the development of a supercell. This is one of many components that are crucial to the formation of a mesocyclone, and aids in the process of tornadogenesis. Strong low-level tropospheric winds and directional shear will generate high values of storm-relative helicity.
