There are occasions when the trade winds that blow west across the tropical Pacific are stronger than normal. This leads to increased upwelling off South America and hence the lower than normal sea surface temperatures. These winds pile up warm surface water in the West Pacific.

The best way to determine the direction of prevailing winds at your home or business is to document the wind direction each day for a period of time. You can do this by setting up a weather vane or simply going outside and stand facing into the wind.

(2 pts) The longitudes in Figure 2 that would support the strongest convection and highest rainfallwould be 120-180-degrees E due to the expectations during a traditional El Nino.

Generally, prevailing winds blow east-west rather than north-south. This happens because Earth’s rotation generates what is known as the Coriolis effect. The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

The speed and direction of the wind is governed by three forces; the pressure gradient force (PGF), the Coriolis Force and friction. PGF is the force produced by differences in barometric pressure between two locations and is responsible for the flow of air from an area of high pressure to an area of low pressure.

Easterly winds can bring very cold spells of weather, in fact it is winds from the east that produce our coldest weather.

In Chapters 10 and 14 of Exodus, Moses summons the east wind to bring the locusts that plague Egypt and to part the Red Sea so that the Children of Israel can escape Pharaoh’s armies. Several other references exist, most associating the east wind with destruction. Often, this is destruction of the wicked by God.

Out of the four winds of the Bible, the east wind is the one which is mentioned most often and it is generally described as a very strong, hot and dry wind. The book of Genesis (verses 41:6, 41:23, 41:27) talks of the heads of grain that sprouted and then got withered by the scorching east wind.

Wind from the East, fish bite the least. Wind from the North, do not go forth. Wind from the South blows bait in their mouth.” The saying is mostly true. The wind can stir up the food chain and provide more cover from the sun due to the action of waves.

If you’re in the United States, you might encounter an east wind on rare occasions. In general, the winds that cross the United States come from the west. These are known as the “prevailing westerlies” and they affect much of the Northern Hemisphere between 30 and 60 degrees north latitude.

The east wind blows from Babylon, across the Arabian Desert, and withers, wilts, and destroys everything in its path. A belly full of the east wind is a poisonous spirit. And again he saith: If my people shall sow filthiness they shall reap the east wind, which bringeth immediate destruction” (Mosiah 7:30-31).

This is called the Coriolis Effect. The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds—the trade winds—to move from east to west on both sides of the equator across this 60-degree “belt.”

What does a NW or Northwesterly Wind Direction Mean? The result is that an east wind, for example, would cause a balloon to follow a westerly bearing, and regarding your specific example, a NW wind is a wind that would carry a balloon toward the southeast.

Wind speed describes how fast the air is moving past a certain point. This may be an averaged over a given unit of time, such as miles per hour, or an instantaneous speed, which is reported as a peak wind speed, wind gust or squall.

Wind direction is defined as the direction the wind is coming from. If you stand so that the wind is blowing directly into your face, the direction you are facing names the wind. That’s why a north wind generally brings colder weather temperatures to Chicago and a south wind implies a warmup.

The staff part of a wind barb shows wind direction. The dot end of the staff is where the wind is blowing to, while the top of the staff shows the direction from which the wind is coming. The top row of wind barbs in the figure to the right all indicate a north wind.

A small, open circle indicates that the winds are calm. This usually means that the wind speed is less than 1.74 knots (2 mph). A single short line (half line) or “feather” represents 5 knots (5.75 mph) of wind speed. A single long line (full line) or “feather” represents 10 knots (11.50 mph).

A balloon provides a simple example of how a rocket engine works. The air trapped inside the balloon pushes out the open end, causing the balloon to move forward. The force of the air escaping is the “action”; the movement of the balloon forward is the “reaction” predicted by Newton’s Third Law of Motion.

Answer: Since air has no definite shape, when air in the balloon escapes, the shape of the balloon changes all the time. The forces acting on the surface of the balloon change direction accordingly, causing irregular path.

When the end of the straw is aimed backward, the air pushes your car forward, as described by Newton’s third law of motion. The more you inflate the balloon the more potential energy it stores, which in turn is converted to more kinetic energy, according to the law of conservation of energy—so the car will go faster.

One is that atmospheric pressure is dramatically reduced at high altitudes, so a helium balloon expands as it rises and eventually explodes. If you inflate a balloon beyond its limits at room temperature, it will break into small pieces up to about ten centimetres long.
