水掛生於水上，纏綿而弱，然登陸則猶能為害。此二者，其旋自地而升，非自雲而降，與正龍掛異其本焉。
This overgeneralizes waterspouts. NOAA says waterspouts come in two types: fair-weather waterspouts, which form upward from the surface, and tornadic waterspouts, which develop downward in thunderstorms and can be as dangerous as land tornadoes.
Full reasoning
NOAA explicitly states that waterspouts fall into two categories:
- Tornadic waterspouts — these are tornadoes that form over water, or move from land to water. NOAA says they have the same characteristics as a land tornado, are associated with severe thunderstorms, and develop downward.
- Fair-weather waterspouts — these are the type that develop on the water surface and work upward, and are generally smaller and less dangerous.
Because of that distinction, it is incorrect to describe all waterspouts as weak, surface-upward vortices fundamentally unlike ordinary tornadoes. That description fits only fair-weather waterspouts, not tornadic waterspouts.

Waterspouts fall into two categories: fair weather waterspouts and tornadic waterspouts. Tornadic waterspouts are tornadoes that form over water, or move from land to water... While tornadic waterspouts develop downward in a thunderstorm, a fair weather waterspout develops on the surface of the water and works its way upward.
- National Weather Service: Waterspouts
Depending on how they form, waterspouts come in two types: tornadic and fair weather. Tornadic waterspouts generally begin as true tornadoes over land in association with a thunderstorm... Fair weather waterspouts... develop at the surface of the water and climb skyward.

The 1054 tornado record was not in England at Kilpeck. Meteorological references place the earliest known European/British Isles tornado at Rosdalla, County Westmeath, Ireland, while the earliest known UK tornado is London in 1091.
Full reasoning
This sentence appears to conflate two different places.
Meteorological reference sources identify the 1054 event as occurring at Rosdalla, near Kilbeggan, County Westmeath, Ireland, not in England at Kilpeck. TORRO states that the earliest tornado known in Europe occurred there on 30 April 1054. It separately states that the earliest tornado known in the UK struck St. Mary le Bow in London on 23 October 1091.
The Met Office library record for the 1054 event likewise describes it as “Rosdalla, County Westmeath, Eire” and notes that it occurred 37 years before the famous London case of 1091.
So the article’s placement of the 1054 event in England/Kilpeck is wrong; the 1054 case belongs to Ireland, and the earliest UK case is 1091 London.

Abstract: ... This undoubted tornado occurred 37 years before the famous London case of October 1091, which has hitherto been regarded as the earliest definite tornado on record in the British Isles.
