Is it safe to fly in rainy days?

Look what rain it is. Generally speaking, if there is no strong convective weather and ordinary rain, there will be no security risks.

Because many of my friends are air traffic controllers, I still have some understanding of this problem, and then I will do some simple science popularization.

Before discussing the flight problem, let's actually learn about the flight altitude of the aircraft and the layered structure of the atmosphere.

Let's talk about the stratification of the atmosphere. In fact, the atmosphere can be divided into different levels according to different attributes in the vertical direction. Generally speaking, from the surface to the sky, it is mainly divided into the following layers: troposphere, stratosphere, mesosphere, thermosphere and escape layer.

The two layers that affect aircraft flight are mainly troposphere and stratosphere. The height of the middle layer and the other three layers is greater than the flying height of the aircraft, so it will not be discussed.

Troposphere, as its name implies, is the layer where convection occurs, and the air activity is strong. Friends who usually fly know that the flight broadcast often says, "Ladies and gentlemen, our plane encountered a strong airflow during the descent, and there was a bump ..." This bump was actually caused by the airflow activity in the troposphere.

The stratosphere, as the name implies, is very flat, which is also the height at which our plane flies. The lower part of the stratosphere is cold and the upper part is warm, so the stratosphere is extremely stable (PS: cold air will sink and warm air will rise, so air convection will occur between cold and hot).

From the above description, we can find that the flight conditions of aircraft mainly depend on the weather conditions in the troposphere. If there is no strong air movement in the troposphere, it will not cause safety hazards to the take-off and landing of aircraft. On the contrary, there may be some persistence, which will cause the flight to be delayed.

So under what circumstances will there be strong air movement? -heavy precipitation weather. Because heavy precipitation weather is often accompanied by strong convection. For example, thunderstorms in summer are caused by strong convection (or mesoscale weather system).

In other words, ordinary light rain will not have strong convection, there will be no safety hazards, and you can fly with confidence. In fact, at present, the aviation meteorological detection technology in China has been relatively stable. According to my friends in the air traffic control bureau, they are always staring at all kinds of real-time monitoring charts, and they are not alone in making relevant forecasts.

So generally speaking, as long as the plane can take off, there will be no so-called security risks. So don't worry, if you really don't worry, you can pay attention to the relevant weather conditions a few days before the flight ~
