Will there be a cloud of airplanes in winter? When can you see the plane cloud

Yes, Wake Clouds of Aircraft Not all aircraft can create such wake clouds, and wake clouds can only be produced when jet planes are flying in layers below --20, when the air humidity is close to or saturated, and when the atmosphere is relatively stable. The principle of wake cloud formation is that when the jet plane flies at a high altitude with a relatively cold and high water vapor content, the exhaust gas ejected from the tail of the aircraft becomes an "aerosol catalyst" for artificial cloud formation, so that the low temperature and high humidity air condenses into cloud bands.

Another process in which wake clouds are generated is when an aircraft is flying in near-saturated air, and the air near the tips of the propellers and wings is adiabatic and cooled by dynamic depressurization, but this is a rare occurrence. There is also a phenomenon similar to the wake cloud, which is called "evaporation wake".

It is the exhaust gas of the aircraft flying in the thin clouds at high altitude to the heating effect of the ambient air is greater than the humidification effect, the mixed air due to the increase in temperature, the relative humidity decreases, the result is that the original cloud layer evaporates, forming a long cloudless blue gap in the white cloud, which is the evaporation wake. When the airplane is performing an air show, it will consciously circle in the air, so it pulls out a ring-shaped wake cloud at the tail, which is very beautiful. Sometimes a dozen or two dozen planes fly in a line, forming a dense wake cloud, which is spectacular.

Usually, when aircraft are on military missions, in order not to expose themselves early, they must follow the weather forecast and avoid entering clouds that can form wake clouds. On the contrary, they sometimes use the plane trail cloud to confuse the other party and make themselves flee quickly. In countries with advanced aviation industries, such as North America and Western Europe, wake clouds have had a direct impact on high cloud cover.

Some scientists believe that wake clouds are artificial cirrus clouds, and a large number of wake clouds will cause an unconscious effect of artificial weather modification.

Yes: This phenomenon is due to the condensation of hot air from high-altitude aircraft engines, which liquefies into small water droplets, which is very common, and wake clouds can generally remain for about an hour. Satisfied.

Aircraft cloud, aka, aircraft wake. Condensation is a visible trail formed by concentrated water vapor expelled from an aircraft engine. As the exhaust fumes from the hot engine are cooled in the air, they can condense to form a cloud of tiny water droplets.

If the air temperature is low enough, the airplane cloud may also be made up of tiny ice crystals. The wingtip vortex dragged from the tip of the wing or flaps is sometimes partially visible due to condensation of water vapor in the core of the vortex. Each whirlpool is a large swirling expanse of air, and the air pressure in the center of the whirlpool is very low.

This wingtip vortex has nothing to do with the exhaust fumes from the engine. Wingtip vortices are sometimes referred to as steam trails. Condensation caused by engine exhaust gases, the main products of hydrocarbon fuel combustion are carbon dioxide and water vapor.

At low temperatures at higher altitudes, the increase in local water vapor can cause the water vapor content in the air to exceed the saturation point. These vapors then condense into tiny water droplets and deposit small amounts into ice crystals. Thousands of small water droplets and/or ice crystals form airplane clouds or condensation endings.

The main component of clouds is water floating in the air. Water vapors that are excessively cooled at high altitudes require a trigger condition to stimulate their condensation or precipitation. It is this trigger that the particles in the engine exhaust gases cause the water vapor in the air to quickly turn into ice crystals.

Aircraft clouds or condensations typically occur above 8,000 m (26,000 ft) above sea level, where temperatures can be as low as -40 °C (-40 °F). The wing of an airplane causes a drop in air pressure near the wing, which leads to a drop in temperature. The combined effect of air pressure and temperature drops causes water in the air to condense and form trailing edge vortices.

This effect is more common in wet weather. Trailing edge vortices are commonly found behind the flaps of airliners during takeoff and landing, during space shuttle landings, and on the surfaces of the upper wings of military jets performing high-intensity exercises. In addition, the air pressure in the area around the vents of the turbofan engine will be lower than the air pressure of the surrounding air and may lead to the formation of condensation fog in the vents of high-thrust units.

These types of steam trails are in contrast to other condensation endings caused by the combustion of jet fuel. Condensation from jet engine exhaust fumes is common at high altitudes and appears at the rear of every engine. Conversely, vapor wakes due to a drop in air pressure are common at low altitudes with high humidity and at the rear of the wingtips and flaps rather than at the rear of jet engines.

The plane flew over for a while. To be in the daytime.

Only when you look down from the sky can you realize what a sea of clouds is. Oh.

Because the water vapor ejected by the airplane is hot, and the air is colder at higher altitude, the gas cools down rapidly and becomes water vapor in the sky, that is, the airplane cloud is metaphorically high above in love, unreachable, not real, but beautiful and satisfying.

This is very normal, we all know that when it rains, the sky will be cloudy, and there will be dark clouds in the sky.

The so-called dark clouds are clouds with more water vapor and higher density, which are denser and more electronically active than white clouds (that is, the probability of generating thunder and lightning will become higher), and the temperature is also different, so the overall dark clouds will be more likely to form rain than white clouds.

Why water vapor is colorless but there are white clouds and dark clouds, in fact, it is because dark clouds are generally thicker, water vapor is more droplets, and it is much more powerful than white clouds in absorbing and scattering sunlight, we see things by the refraction of light, if an object absorbs all the light, you will not see it, or you will not be able to see it clearly when its scattering is stronger.

It's a bit like watching things at night, when there's less light, things are black.

That's not why, the clouds are different, and the black clouds mean that the water vapor is heavier.

Black clouds should be raining and heavy water vapor.

The high temperature and water vapor generated by the aircraft after burning the oil will quickly condense into small water droplets when it encounters cold air at high altitude, and it will not be blown away in a short period of time when there are no clouds in the high altitude and the wind is not strong, forming the tail of the aircraft"Cloud"。

It is not the appearance of clouds, but the pollutants caused by the burning of aviation gasoline by aircraft.

It is the smoke formed by the exhaust fumes of the aircraft.
