Its probably because of what you are used to, its like whenever it does snow down here everything grinds to a halt, because a lot of snow is 'relatively' rare here the local councils won't spend money on the right kind of equipment so that when it does come they are woefully short of what's needed ie snowploughs etc. Do you know if the Humber bridge or the Forth bridge ever close because of high winds?

Probably because of their population density and the number of services going on through each station.

I'm going through Farringdon tomorrow and something like 50 trains go through an hour? Something simple would mess tghe rhythm of that up easily.

Trees in Southern England are smaller and more feable.

I don't see too many sturdy Norweigan Spruce around here, for example.

I think maybe you mean the trees are more long/thin like a stick

Trees in climates that are not windy have weaker root systems and grow taller than in windy climates. Eucalyptus trees always collapse when we have winter storms. There are also far higher density of trees in London compared with pretty much any other city in the UK. Surrey, just outside London, is the most heavily vegetated county in the UK.

Chicago is not the "Windy City" in terms of being windy, though we do get some very strong storms that can produce very high winds at times.





How does London compare annually and seasonally?

Heathrow, which is the windiest of the London stations, has an annual average wind speed of 7.7 mph.
The windiest month is January: 8.7 mph average
The least windy month is September: 7.0 mph average

Kew Gardens, which has more representative wind speeds for the area (not being an airport), has an annual average wind speed of 6.2mph, ranging from 7.2mph in January, to 5.0mph in September.

Highest wind speed ever recorded was an 87mph gust in January 1990. In 2nd place is a 76mph gust in October 1987.

Yeah ORD is largely wind swept being a massive airport, but I bet Northerly Island on the lakefront would have even greater wind speeds here...

A wider look shows that the 10mph annual winds is quite small likely lake influenced and encompasses ORD. Most of the area is between 8-9mph

The climate here isn't windy, but gusts of 50mph wouldn't be considered a noteworthy storm.

I think Southern England has a landscape/climate/fauna more akin to the low countries of mainland Europe rather than the rest of Britain. The trees are clearly of the thin variety, something that isn't common in the rest of Britain

The most common trees here are oak (red, pin, English, holm), ash, pine, sycamore, sweet and horse chestnut, beech, walnut, plane, poplar, rowan, locust, laurel, eucalyptus, holly, cherry (inc. plum, apricot, almond), apple, willow, magnolia, cypress, cordyline, alder.

Most of those are not 'thin' (Lombardy poplars are the only common tree I would describe as thin). Birch trees are thin and are more common outside the SE.

Didn't you once say that the vegetation in SE England looked Spanish?!?!
