England ... (has) one of the world's highest rates of tornadoes, relative to its size.

That seems a silly statement unless you live in Birmingham. This was some of the aftermath of a F2 tornado in 2005:

2:30 BST 28 July 2005: a F2 Tornado hit Sparkbrook, Birmingham & 1km of the city

95% of the UK tornadoes are at the bottom of the scale (F0/F1).

(Fujita scale; Developed in 1971 by T. Theodore Fujita of the University of Chicago):

  1. F0: Winds < 73 mph (< 117 kph) Light damage
    Some damage to chimneys; branches broken off trees; shallow-rooted trees pushed over; sign boards damaged.
  2. F1: Winds 73-112 mph (118-180 kph) Moderate damage
    Peels surface off roofs; mobile homes pushed off foundations or overturned; moving cars blown off roads.
  3. F2: Winds 113-157 mph (181-253 kph) Considerable damage
    Roofs torn off frame houses; mobile homes demolished; railway boxcars overturned; large trees snapped or uprooted; light-object missiles generated; cars lifted off ground.
  4. F3: Winds 158-206 mph (254-332 kph) Severe damage
    Roofs and some walls torn off well-constructed houses; trains overturned; most trees in forest uprooted; heavy cars lifted off the ground and thrown.
  5. F4: Winds 207-260 mph (333-418 kph) Devastating damage
    Well-constructed houses levelled; structures with weak foundations blown away some distance; cars thrown and large missiles generated.
  6. F5: Winds 261-318 mph (419-512 kph) Incredible damage
    Strong frame houses levelled off foundations and swept away; car-sized missiles fly through the air in excess of 100 meters (109 yds); trees debarked; incredible phenomena will occur.

The University of Manchester has taken all reports of UK tornadoes between 1980 and 2012, and has mapped the results:-
