Does wind ever blow straight up or down?

Question

I remember in Forrest Gump, in Vietnam, he mentions that the rain fell straight down, slantways, sideways and even up. I know that rain at ground level could not be carried up, but does wind ever blow upwards at ground level.

Answer 1

Ever see a vulture souring? They glide on updrafts, where warm air from ground level rises against hills or bluffs. Hail is formed by sever updrafts in thunderstorms. Rain is blown up into the clouds, freezes, comes back down and blows up again to form hail. When it gets too heavy for the wind to blow it up again, it falls to the earth.

How about a down draft? Planes crash because down drafts force them to the ground. Trees are snapped off, midway up the trunks with down drafts.

The answer is, yes.

Answer 2

My answer applies to controlled airports in the U.S. while the wind is decrease than 5 knots, the "Calm Wind" runway would be used. The runway that's exact because of the fact the calm wind runway does not exchange, and is frequently the runway that's maximum aligned with the historic wind course. The designation of this runway is made through the airport operator and Air site visitors administration (ATC). it extremely isn't any longer uncommon for the runway in use to be mis-aligned with the wind while the wind is decrease than 5 knots. while the wind is 5 knots or extra, ATC will use the runway maximum aligned with the wind. whether, there are exceptions to this: maximum important airports have what's talked approximately as a "runway use software". as a consequence, ATC will assign runways that have the least effect on noise. The pilot is often expected to propose ATC if a various runway than that assigned is favored. At airports the place there's a runway use software, that's extremely consumer-friendly to be certain takeoffs and landings on runways that don't align with the wind. frequently, a 10 knot tailwind is the cutoff, with adjustments reckoning on the runway subject and braking action. each and every airplane has it extremely is very own optimal tailwind ingredient. submit to in recommendations, a 10 knot quartering tailwind quantities to diminish than 10 knots of tailwind ingredient.

Answer 3

I'm watching that movie right now :) I think in his context the rain was coming upwards because it was splashing off of the 'flood'. But to answer your question, yes wind (well, air) does move vertically - this happens in rain showers, thunderstorms, frontal passages, etc. Vertical motion meaning that air is moving upwards as well as downwards. Vertical velocities upward are called updrafts; downward called downdrafts. Vertical motion plays a huge role in aviation... planes must avoid it.

Answer 4

Wind does go up and down, a lot of times in a thunderstorm, you up drafts and down drafts, These down drafts or down bursts can be very dangerous if you are a pilot of an airplane.

Answer 5

wind can never blow straight. its always in a swirling motion.
look at trees in the wind. the leaves don't move in the same motion.

Answer 6

We can't know wind will blow to which direction.

Answer 7

yep,
updrafts and downdraft are just that
Wind blowing up or wind blowing down

Answer 8

Winds goes up and Down.....

Answer 9

straight up pilot call it wind shear

Answer 10

I'm going to guess that somewhere on the Earth it has happened.
