Clouds

Condensation nuclei are tiny particles in the atmosphere on which water vapor condenses to form clouds or fog. These nuclei can be dust, salt particles, or pollutants. They are crucial for cloud formation as they provide a surface for water vapor to condense onto, initiating the cloud formation process.

A cloudy day refers to a day when a significant portion of the sky is covered by clouds, resulting in limited visibility of the sun or sky. Cloudy days can vary in terms of the thickness and types of clouds present, impacting the amount of sunlight that reaches the ground.

When it is hot out and the sun is shining above the water evaporates is called water vapor. So then this keeps happening it keeps making water vapor it makes clouds. And later on it will rain, snow, hale, or have sleet.Thanks for reading!

It depends, a barometer can measure many different types of air pressure and there are different kinds of air pressure. your best bet would be to identify what type of barometer you have and simply read a dial. If you don't have a barometer and would just like to know what the maximum registered amount for high pressure is then you should consult you weather records centre. These following records i believe are the most up to date: 1085.6 mb in Mongolia. The lowest recorded air pressure is 850 mbar in Manchester, South Dakota. In theory a barometer can record any amount of air pressure depending on its size. The larger the barometer, the greater range of measurement of air pressure. Currently the worlds largest Barometer resides in the Denmark Visitor Centre. You can find more about this Barometer at: http://www.bertbolle.com/

Any cartel is a set of people, companies, countries, which have such a strong control over some commodity that others wish to buy, that they agree not to compete with each other for sales, but all offer to sell at the same price. The customer is thus held to ransom because there is not a free competing market. A famous example is oil, but others exist in food, minerals etc.

A warm air mass that is cut off from the ground is said to be an aloft air mass.

Warm air tends to rise due to its lower density compared to cold air, which causes it to be displaced by cooler, denser air. As warm air rises, cold air takes its place, creating a circular motion known as convection currents. This movement happens because warmer air expands and becomes less dense, leading it to ascend while colder air contracts and sinks.

Weather moves around the world due to the rotation of the Earth, the heating and cooling of the atmosphere, and the distribution of heat energy from the sun. This creates differences in air pressure that drive the movement of air masses, causing weather systems to form and move across the globe.

Clouds form from water vapor in the air that condenses into water droplets or ice crystals. This condensation occurs when the air reaches its dew point, causing the water vapor to change into visible cloud particles.

Adiabatic cooling relates to cloud formation in such, when it pushes air out of the way when rising, energy is released into the surroundings and the air cools "adiabatically." When the air that is cooling meets up with other air that is in the same situation, a cloud starts to forms, and when that cloud forms, it cools enough when it reaches a certain altitude and rains.

The vapor blanket around the sun is called the solar corona. It is the outermost layer of the sun's atmosphere and is composed of highly ionized gas that is visible during a total solar eclipse.

Cloud formation involves three main processes: 1) evaporation of water from the Earth's surface, 2) condensation of water vapor into tiny droplets or ice crystals in the atmosphere, and 3) the aggregation of these droplets or crystals to form visible clouds.

Cloud seeding uses Silver Iodide to provide nuclei for water to form droplets on. Like most chemicals, Silver Iodide can be harmful if ingested in large quantities, but this requires massive and/or continued exposure.

Studies in 1977 and 1981 showed minimal residual traces after cloud seeding.

Approximately 50 tons are used each year for this purpose, which is a very small amount in comparison to the total volume of the atmosphere.

The effectiveness of cloud seeding is debatable - several organizations have given up on trying to use it in a systematic manner - eg the US National Oceanic and Atmospheric Administration (NOAA) gave up trying to mitigate hurricanes with cloud seeding in 1968

Rumors linking cloud seeding to the chemtrail hoax exist, however barium is not used for cloud seeding.

The change of a liquid to a gas is Vaporization. Not to be confused with "Evaporation".

WD-40 remains a liquid both in the can and out. This incredible substance can lubricate any metal part, and it is also on an excellent bug killer.

The two main types of fog are advection fog, which forms when warm, moist air moves over a cool surface, and radiation fog, which forms when the Earth's surface cools down rapidly by radiating its heat into the atmosphere.

The row of thunderheads that builds up in front of advancing cold air is called a squall line. This line of strong thunderstorms typically forms along a cold front as warm moist air is lifted rapidly by the advancing cooler air. Squall lines can produce severe weather such as strong winds, heavy rain, and hail.

Water vapour is like air so if you condense it (cool it down) then it will turn into water (a liquid). I hope this helped!

The angular size of the cloud would depend on its length and how far it extends from directly overhead to the horizon. Assuming the cloud is very long and extends all the way to the horizon, it would have a wide angular size approaching 180 degrees when looking from directly underneath it.

Surface elevation can affect air pressure, which in turn influences the amount of water vapor the air can hold. Higher elevations typically have lower pressure and cooler temperatures, leading to lower water vapor capacity. This can result in drier and less humid conditions at higher elevations compared to lower elevations.

Winds are generated when air flows from a high pressure area into a low pressure area. This movement occurs due to the pressure difference, with air moving from areas of higher pressure to lower pressure to equalize the pressure gradient.

Air pressure plays a significant role in determining weather patterns. High pressure systems generally bring fair weather, while low pressure systems can lead to storms and precipitation. Changes in air pressure can influence wind patterns and temperature, affecting weather conditions at a given location.
