De windrichting op alle hoogtes is hier boven NL gelijk. Klopt het dat dit (hoogstwaarschijnlijk) lijnvormige buien/clusters oplevert?
Het is vooral de toename van de snelheid, bij gelijkblijvende richting die leidt tot de lijnvorming.
"CASE 2: STRONG SPEED SHEAR, WEAK DIRECTIONAL SHEAR
This situation is often termed "unidirectional shear". The speed shear will allow the storm to move. The movement insures the storm will last longer than an airmass thunderstorm. Unidirectional shear often produces storms that form into lines (Mesoscale Convective Systems (MCS's)). Since the storm moves, outflow produces lift that enables new storms to grow on the storm's periphery. Over time, a line a storms result. These storms primarily produce small hail, weak tornadoes and heavy rain when they are associated with severe weather."
