Clouds

Neon, ammonia, methane, hydrogen, helium and water vapour are the best lifting gases and are all less denser than air.

Rain occurs when water droplets in clouds combine and grow in size until they are too heavy to be suspended in the air, causing them to fall as precipitation. This process is known as coalescence and is influenced by factors such as temperature, humidity, and air currents.

Clouds can absorb some of the sun's ultraviolet (UV) radiation depending on their thickness and composition. However, clouds primarily act as reflectors of UV rays, scattering them back into space rather than absorbing them. This can lead to varying levels of UV exposure on the Earth's surface depending on cloud cover.

The emission of water vapors from volcanoes is called volcanic steam or volcanic emissions. Water vapor is one of the primary gases released during volcanic activity, along with carbon dioxide and sulfur dioxide.

The air that contains water vapor in equilibrium at a certain temperature is called saturated air. At saturation, the air has reached its maximum water vapor capacity at that temperature, leading to a balance between evaporation and condensation.

Cold fronts can vary in speed, but typically move at an average speed of 20-30 miles per hour. However, certain factors like the intensity of the front, the time of year, and local weather conditions can affect the speed at which a cold front moves.

It really doesn't change in speed. The jet stream is considered to be when the wind reaches 50 mph. In the United States, the jet streams tends to dip down from Canada and provide us with stronger westward winds. That is why you will see airplanes schedules tend to have two different times tables in the winter when flying west or east.

Inhaled air is typically warmed and humidified as it passes through the nasal passages. The purpose of this process is to protect the delicate tissues of the respiratory system from damage due to cold and dry air.

Mammatus clouds do not predict specific weather events. They typically form in association with strong thunderstorms or severe weather but are not indicative of the severity of the upcoming weather. They are more of a phenomenon associated with turbulent atmospheric conditions.

Those are known as stratocumulus clouds. They typically form layers with flat, broad bases and usually indicate stable atmospheric conditions, making fair weather likely.

Seeing a rabbit shape in a cloud is simply a unique and interesting natural phenomenon. There is no universally accepted meaning attributed to this specific shape, as it is subjective and open to personal interpretation. It can be seen as a fun and whimsical moment, prompting creativity and imagination.

The layer you are referring to is the mesosphere, which is located above the stratosphere and extends up to about 80 km above the Earth's surface. In the mesosphere, temperatures can drop as low as -90°C or even colder. This region plays a crucial role in filtering out meteoroids and other space debris entering Earth's atmosphere.

Pay close attention to your question. A maritime (meaning oceanic) air mass has moisture, therefore it's not dry. Polar (meaning from the polar region) air mass is cold, therefore it is cold. Hence a maritime polar air mass would be moist and cold...how hard was that?

Polluted areas can be cloudier because pollutants such as smoke, dust, and particulate matter can scatter sunlight and create a haze in the atmosphere. This can lead to reduced visibility and a higher concentration of particles in the air, which can contribute to cloud formation.

No. Stratus clouds are low level, usually flat clouds that can bring rain or snow but usually do not indicate hazardous weather. A funnel cloud is a rotating downward projection of a cumulonimbus that is often cone shaped.

Cutting trees reduces the amount of moisture (and oxygen) in the state. If you spend much time in WV in the summer, you will find the air moving in the woods to be cooler and feel much more moist to the skin.

If you are in a hollow and the air is sweeping up the hollow, in dense forest, it's down-right cold. Goose-bumps for sure!

Water falls from clouds in the form of rain because the droplets of water in the clouds grow too heavy to remain suspended in the air. This happens when the water droplets coalesce and become too large for the cloud's updrafts to keep them aloft, leading to them falling to the ground as precipitation.

I have evidence that atmospheric (barometric) pressure affects us as humans. When pressure is low the body feels like a brick. There seems to be a lot of evidence of this, so where are the studies?

That process is called precipitation. It occurs when water droplets or ice crystals in the clouds become too heavy to remain aloft and fall to the ground under the influence of gravity. This can take the form of rain, snow, sleet, or hail depending on the atmospheric conditions.

Clouds at high altitude use the prefix cirro while clouds at middle altitude use the prefix alto. I know this is not in the question but clouds at low altitude don't use any specific prefix. I am also in love with Arturo B.

An approximate value can be calculated by the following expression: Condensation Level (in feet) = [Surface Temperature(F) - Surface Dew Point Temperature(F)]*(1000/2.2) or Condensation Level (in meters) = [Surface Temperature(C) - Surface Dew Point Temperature(C)]*(200) Solution: Dry Adiabatic Lapse Rate (DALR) => -5.5 F/1000 ft of altitude (-1C/100m) Saturated Adiabatic Lapse Rate (SALR) => -3.3F/1000ft of altitude (-0.5C/100m) The SALR is not linear and varies with the initial surface temperature The Level of Condensation will occur at the altitude where the Air Temperature is equal to the Dew Point temperature at that altitude. Setting the two equations equal to each other will give an approximate value. TA: temperature at altitude; TS: temperature at surface; DA: dew point temperature at altitude; DS: dew point temperature at surface TA = TS-(5.5F/1000ft)*altitude or TS-(1C/100m)*altitude DA = DS-(3.3F/1000ft)*altitude or DS-(0.5C/100m)*altitude Setting TA = DA and rearranging quantities gives the equations given above The level of condensation derived by the above method will only yield an approximate value.

The main conflict in the book "The Death and Life of Charlie St. Cloud" centers around Charlie's struggle to move on from the death of his younger brother, Sam. This internal conflict is exacerbated when Charlie starts to see and communicate with Sam's spirit, leading him to question his own sanity and his ability to let go. Additionally, there is an external conflict when Charlie is torn between his promise to his brother and his burgeoning feelings for a woman named Tess.

Ozone particles; part of the ozonosphere.

The troposphere is the lowest layer of the Earth's atmosphere where most weather occurs. Cloud formation in the troposphere depends on factors such as temperature, humidity, and atmospheric dynamics. If these conditions are not favorable, there may be few or no clouds present in the troposphere.
