What causes the development of most clouds and precipitation in the atmosphere ??
Rising warm air cools, resulting in cloud formation and rain. Why does rain occur near a warm front? Rising warm air cools, resulting in cloud formation and rain. What causes the development of most clouds and precipitation in the atmosphere?
What is the scientific name for the dark tall puffy clouds that indicate a thunderstorm is coming?
Cumulonimbus clouds are menacing looking multi-level clouds, extending high into the sky in towers or plumes. More commonly known as thunderclouds, cumulonimbus is the only cloud type that can produce hail, thunder and lightning.
Why are you more likely to get sunburned if you visit a low latitude location compared to a high latitude location?
Why are you more likely to get sunburned if you visit a low-latitude location compared to a high-latitude location? Solar rays strike low-latitude locations most directly. so that the North Pole tilts toward the Sun.
What happens when there are extreme differences in air pressure and temperatures?
When there are extreme differences in air pressure and temperatures, violent storms often occur, including hailstorms and tornadoes.
When air rises it is forced to cool when this occurs Why do you think clouds form?
When air rises in the atmosphere it gets cooler and is under less pressure. When air cools, it's not able to hold all of the water vapor it once was. Air also can't hold as much water when air pressure drops. The vapor becomes small water droplets or ice crystals and a cloud is formed.
What causes precipitation to occur in the atmosphere?
Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth. If a cloud is colder, like it would be at higher altitudes, the water droplets may freeze to form ice.
Which weather phenomenon signals the beginning of the mature stage of a thunderstorm?
Which weather phenomenon signals the beginning of the mature stage of a thunderstorm? Precipitation beginning to fall.
What clouds produce tornadoes?
Cumulonimbus These are sometimes called anvil clouds because of the way the upper-level winds shear the tops of the clouds and push them to one side. Meaning: Strong thunderstorms are likely and severe storms are possible. Hail, high winds and tornadoes could accompany any severe thunderstorms that develop.
How does the angle of the sunlight that hits the Earth affect the seasons?
The Short Answer: Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
Why do you burn easier near the equator?
The more direct the sunlight in your area is, the greater the dose — so in general, the closer to the equator you are, the greater the chance of sunburn. It's also much higher during summer, and between the hours of 10 am and 2 pm, peaking at mid-day.
Why do high pressure systems rotate clockwise?
Likewise, think of a cell of high pressure surrounded by low pressure. The air flowing out from the centre of the high to the periphery will turn to the right due to the Coriolis force, resulting in a clockwise circulation around the high. In the southern hemisphere, the whole thing is reversed.
Why does air move from high pressure to low pressure?
In areas of high pressure, the gases in the air are more crowded. In low pressure zones, the gases are a little more spread out. You might think that the warm air would lead to a higher pressure area, but actually the opposite is true. Because warm air rises, it leaves behind an area of low pressure behind it.
Why will the continued cooling of a layer of air eventually cause the layer to become saturated?
More commonly in the atmosphere, saturated conditions are achieved by the cooling of air. This occurs because the capacity to hold water vapor decreases as temperature decreases. Consequently, cooling will eventually reduce the water-vapor capacity until it is equal to the amount of water vapor present in the volume.
When warm moist air at the earth’s surface rises up into the atmosphere?
Warm, moist air rises, expands and cools in a convection current. As the air reaches its dew point, the water vapor in the air condenses, forming a cloud. AIR RISES, COOLS, AND CONDENSES. 2.
What causes precipitate to form?
Formation of an insoluble compound will sometimes occur when a solution containing a particular cation (a positively charged ion) is mixed with another solution containing a particular anion (a negatively charged ion). The solid that separates is called a precipitate.
What is precipitation short answer?
Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow.
Which weather phenomenon will always occur when flying across a front?
One weather phenomenon that will always occur when flying across a front is a change in the wind direction. Additionally, one of the most easiest recognizable changes when flying across a front is a change in temperature.
What are the three stages in the development of a thunderstorm?
Thunderstorms have three stages in their life cycle: The developing stage, the mature stage, and the dissipating stage. The developing stage of a thunderstorm is marked by a cumulus cloud that is being pushed upward by a rising column of air (updraft).
Why do tornadoes spin in a circle?
At low levels, air spirals into a tornado in a large counter-clockwise circle many times the width of the tornado itself. The direction of this spin is due to the Coriolis effect: a phenomenon caused by the Earth's rotation, which imparts a deflection to the right of the intended path of a body in motion.
How are tornadoes formed?
Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing an updraft. The updraft will begin to rotate if winds vary sharply in speed or direction.
How do the latitude and the tilt in the axis of rotation of the Earth affect the amount of radiation received at the Earth’s surface?
The higher the latitude, the less is the angle the rays make with the surface of the earth resulting in slant rays. The area covered by the vertical rays is always less than the slant rays. If more area is covered, the energy gets distributed and the net energy received per unit area decreases.
Why is the tilt of the Earth a big factor in changing seasons?
The Short Answer: Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
Do you sunburn faster when wet?
And remember that you can get sunburned more quickly when you're swimming or boating because the reflection from the water makes the sun's rays stronger.
Does peeling skin contain DNA?
Because your skin cells' DNA is damaged, the dead cells slough off, which leads to peeling. How can I treat a peeling sunburn?
Why does air flow counterclockwise in a low-pressure system in the Northern Hemisphere?
Because of Earth's spin and the Coriolis effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator.
What causes the Coriolis effect?
Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect.
Why does air at the equator rise?
Atmospheric Convection. The Earth is most strongly heated near the equator. Surface air is heated and expands as the temperature increases, thereby decreasing the density of the air. This low density air rises over the equator, and is replaced by surface air streaming from north and south of the equator.
What causes air to circulate vertically and horizontally in relation to the surface of the Earth?
The pressure gradient causes the air to move horizontally, forcing the air directly from a region of high pressure to a region of low pressure. The Coriolis force, however, deflects the direction of the flow of the air (to the right in the Northern Hemisphere) and causes the air to flow parallel to the isobars.
Why did the rising air in the cloud eventually stop rising or start falling )?
This allows the parcel of air to rise until all of the 'surplus' water vapor has condensed and all the latent heat has been released. Therefore, the main reason which stops clouds growing upwards is the end of the release of latent heat through the condensation process.
Why does air become saturated?
Air can become saturated due to evaporation, the mixing of two unsaturated air masses or by cooling the air. Water vapor in the atmosphere condenses when it becomes saturated and bumps into condensation nuclei. Nuclei are particles. Water vapor and liquid water can condense onto these nuclei.
