They're now building towers, like 7 South Dearborn in Chicago, with notches built into the sides every 20 stories or so, reducing wind pressure by 10% to 15%--especially important in hurricane-vulnerable New York.
Tornados are rated on several scales for strength based either on wind speed, pressure drop, or damaged caused, but the updated Enhanced Fujita Scale is the presently accepted scale in the United States.
Temperature, rain, cloud cover, barometric pressure, wind speed and humidity had no affect.
FORBES: Make Your Own Sunshine: Weather And Happiness Are Not Linked
Hurtling towards the stratosphere the balloon was fitted with weather instruments designed to measure, among other things, temperature, pressure and wind speed.
At altitude, notably, for instance, approaching the Himalayas, it is far trickier to grasp just how factors such as wind direction, air pressure, latent heating and moisture levels interact to deliver monsoon rains.
Using a powerful supercomputer, weather forecasters divide the atmosphere up into an elaborate three-dimensional grid, assign initial values of pressure, wind-speed, humidity and so on, and then apply the laws of physics to see what happens next.
The draft legislation comes after months of debate and failed proposals, including retroactive cuts to investment agreements, a full halt in new subsidies for renewable energy projects and a variable tax rate on energy production that sank under pressure from wind and solar sectors already struggling to survive.
On its own, the pressure exerted by the protons and electrons of the solar wind is even more feeble than the photon pressure.
ECONOMIST: Rockets are not the only way to travel through outer space
Chairman of pressure group Ill Wind, Des Fitzpatrick, said he was "confident" the plans would be overturned.
That, along with tougher environmental rules and alternatives such as wind and solar will keep the pressure on coal.
Also, changes in the speed and pressure of the solar wind cause the termination shock to expand, contract and ripple.
"Through embedded sensors, the probes can measure a tornado's wind speed and direction, barometric pressure, humidity, and temperature, " the magazine wrote.
This warmth is quickly absorbed by the air above creating changes in the local air pressure (ie, wind) and mini-thermals on which small algae might rise upwards.
Those characteristics can include a brief dip in air pressure, a change in wind direction, a change in wind speed, a rise in air temperature or a dip in ultraviolet light reaching the rover.
ENGADGET: Curiosity rover finds radiation levels on Mars are safe for humans
The assumptions of a 230 mph wind speed and a 1.2 psi rapid pressure decrease in about 1 second along with large and fast missiles is quite a force to design against.
The highest summer temperatures often associate with stagnant high-pressure systems in which there is very little wind.

And such areas of high pressure are, almost by definition, accompanied by no wind.
Nikora, with a considerable wind behind him, fired over a brilliant conversion to increase the pressure on the Heineken Cup champions.
This is where the "wind" of electrically charged particles coming off the Sun is slowed by pressure from the sparse gas found between the stars.
On the other side, older adults with untreated depression are less likely to have their diabetes, high blood pressure and other physical conditions under control and consequently wind up costing a lot more to treat.
MSN: Boomers will be in need of mental health care, report finds
When there is no wind, for example, heat builds up in a city, creating a low-pressure system that pulls air into the city.
Lionel Djebi-Zadi had retained his place despite being sent off in last week's Scottish Cup defeat by Falkirk and it was his Inverness defence that were under pressure from the kick-off as both sides struggled to cope with the wind swirling in from the Moray Firth.
"It seems to be an Irish solution to a British problem - politically they don't want turbines on the British countryside, they are under a lot of pressure from the general public over there and it seems they want to impose these wind farms on the Irish general public instead, " he said.
BBC: Ireland to build 'giant' wind turbines to power UK homes
Another issue is finding the right tubing that is flexible enough to wind up on a spool but resilient enough to not bend or break, either from internal fluid pressure or by being cut by plants and rocks on the landscape.
FORBES: Startup Aims To Install Pipelines With Helicopters...Seriously!
Usually, the prevailing south-westerly wind would take the ash cloud away from Europe and over the polar region, but a high-pressure area is bringing it over Europe, where it is sitting and barely moving as the ash spreads.
Instead of relying on photon pressure, it would enable a spacecraft to be pushed along by the charged particles of the solar wind itself.
