Interesting point, we are surrounded by a lot of very tall (20-40) floor buildings.

There was pretty weird weather/air-movement around the WTC/WFC in NYC too .... maybe such intensely urban environments, elicit unusual micro-climates.

Architectural Aerodynamics. I doubt serious that much thought was given to that until recently, e.g., the Sail and maybe the Keppel buildings and a few others but it's a big deal when building new skyscrapers today.

Saw a docu on it on one of the Discovery or some such channel on the TV.

I reckon buildings play a much bigger role in our weather than we think.

This doesn't only apply to wind. Think of water run-off; every time a plot of land becomes a building, a car park or a paved area, the rain water there can no longer seep into the ground. Instead, it will collect and will then need to run off. Basically, as more and more fallow land becomes built up, more and more water needs to run off through drains and the like.

Temperature? As concrete is mostly silica, it's excellent at retaining heat. In so doing, built up areas become a heat sink at night, whereas previously those areas, when still wooded, would cool off at night. I think this is one of the reasons why I used to see dew and dew puddles in the early mornings, but now hardly ever do. The mornings aren't as chilly as they used to be.

Then again, it could all be global warming eh.

Looks like a I pulled a reverse Michael Fish here. But that's the weather for you innit.

Anyhoo, tomorrow looks like it may be nice and breezy. And hopefully a little warmer. My water boiler is losing the battle. Wow, Chua Chu Kang barely 22 degrees at 4 pm :o

Yes, I think yesterday morning I got up at c5am to shut banging doors/windows, as I thought there was a big storm coming in. This afternoon I was feeling the breeze, and looking at the trees... pretty strong! So I was looking for the directions of the rain to follow... but I could see none...

Weird isn't it, I wouldn't have thought it possible to feel cold when it's 25c!!

I don't feel cold at all. But at least I did quit perspiring for a while! I had a real blast yesterday. Actually was a good day for washing windows. :-( but at least I got 'em all done.
