There are countries where it rains most of the time and surprisingly, some people love it with all their hearts. The reason is due to its positive impact on the grass and crops. Constant raining makes it healthy and helps its growing process as well.
One important thing is that rain plays a striking role in our lives since it can be used as a good source of water and also rivers and lakes are dependent on it.
Rainfall has different types and one of them is known as convectional rainfall. From the following article, you will get to know all about it. So, keep reading as it is filled with beneficial information.
What is Convectional Rainfall?
This type of rainfall is unique because it happens mostly on warmer days. Just imagine a day when you are enjoying the sun and without any warning, you just experienced that the sky got darker and grey clouds are forming all over.
Moreover, it starts to rain and the whole atmosphere changes within an instant. Some people take this situation as a blessing in disguise while others consider it as a pain in the head. So, it varies from people to people when it comes to this perception.
If you have ever faced this situation, you have encountered convectional rainfall. When it happens, the sky forms cumulus or fluffy clouds and thundery rain occurs.
How does it Happen?
The ground gets heated up due to the sun and this makes the air warmer than its usual temperature. Overall, the surrounding gets hot and within that time, the air slowly starts to rise in an upward direction. It also becomes cool during the process.
Likewise, the air reaches a level where it has cooled to a maximum extent that the water vapor changes to a liquid. This is known as condensation and after that, it starts to form cumulus clouds in the upper atmosphere. When the cloud becomes saturated completely, it starts to precipitate and this gives dense thundery showers.
This process shows that it is possible to get thunder rains during a hot day.
Sadly, the rainfall can turn into a storm in different weather conditions. This had happened to many parts of the world. Areas that have a good water source, intense heat level are considered to be the most vulnerable. The storm is also common in mountains which usually remain warm throughout the summer.
Impact on the Environment Due to Convectional Rainfall
Its effect is severe in the lives of many people. If an aircraft flies into that region when the rainfall is happening, it will experience turbulence. Thus, with the increase in altitude, the temperature will get lower even more.
If there are properties and people are living there, the lighting and thunderstorms could destroy everything. As a result, the lives of the people are also vulnerable.
Accordingly, heavy raindrops can damage crops and vegetations. Not only that, but the economic cost will also rise to overcome the problem.
You never know what kind of convectional rainfall you will experience. If it starts showering giant hailstones, the impact will be severely dangerous on the crop leaves and the peoples well being.
Explanations About the Water Cycle that Leads to Rainfall
You will be surprised to know that the water moves from streams, seas, and rivers and it goes directly to the sky. When it reaches that atmosphere, it starts forming clouds. This is known as the water or hydrological cycle.
This cycle plays a very important role in moving the water to the sky and back to the river again. Yes, without this process, we won’t have streams, seas or lakes. Furthermore, humans or animals won’t be able to survive without the proper supply of water. Have a look at the water cycle stages to gain more information.
The process starts at the sea where the sun warms the water. As the temperature of the water rises, the seawater starts evaporating. Then, this converts to water vapor. After that, another conversion happens and it turns to steam finally. Since it is light, it starts rising as hot air.
With the increase in height, the water vapor starts getting cooler. As the vapor reaches the cooling temperature, it starts to condense. The condensation happens because it is unable to store water droplets.
As the condensation process goes on and on, clouds start to form in the sky. Besides, the clouds constantly receive more and more vapor until it cannot store further. Precipitation gets started after the cloud reaches its full extent.
According to the temperature, precipitation can come in different forms. So, you will either have rain, sleet, hailstones, or snow.
When the rainfall happens, it lands on streams and rivers. These rivers and streams then move the water to the sea again. Hence, the procedure that initiates the cycle gets repeated.
Some Important Facts
- Convectional rainfall happens mostly in humid tropical regions. This kind of area receives most of the sun’s energy and remains warm until the sunsets.
- Most of the time, it starts raining during the afternoon when the surface air gets heated to its maximum level.
- The coastal areas encounter heavy amounts of rainfall than the interior continents. This is due to a huge store of water in the oceans which makes the condensation process much easier than the land.
- Other types of rainfall are relief rainfall and frontal rainfall.
- Relief rainfall happens in areas with mountains and seas. The winds pick up moisture present in the sea as they move across it. Then, the moist air arrives at the coast and rises over the mountains and hills. The air gets cooled and forms clouds from condensation. Air continues to rise over the mountains and it releases the moisture in the form of rain.
- Frontal rainfall occurs when two air masses come in contact with each other. One is warmer and the other is colder. Because one of the air masses is warmer, it starts to rise above the colder one. When the air gets cooled, it starts to form stratus clouds (low-level clouds) through condensation. After it gets saturated, it starts precipitating.
These are all about convectional rainfall. Go through this article a couple of times so that you can get a clear understanding of it. If this rainfall happens in your area, make sure you take the necessary precautions beforehand because you don’t know the intensity of the rain that is going to happen in your environment.
Always carry a wind umbrella when you will go outside (to be on the safer side).
Stay safe and take care!
