Why does rain leave traces on roofs and where does it come from?

Arabia Weather - The sky holds endless secrets, and among these secrets stands out the phenomenon of mud rain, where rain falls accompanied by small particles that enhance its magical moments, and at the same time raise questions about its origin and its impact on the environment and human health.

Surely, you have ever seen cities covered in a layer of mud after rain, which is popularly known as “mud rain” and this is one of the resulting phenomena; Due to rain falling in areas where the air and soil are filtered and purified, and despite the benefits of this rain in improving the quality of the air and soil in general, it leaves behind effects that can be observed after it rains.

This phenomenon is a well-known phenomenon, as cars appear covered in a layer of mud, in addition to pedestrians and buildings also being affected by this layer of mud during this period.

What is mud rain?

Answer: Mud rain is known as a combination of dust and soil particles with water droplets inside the clouds. When rain falls, the rain is mixed with dust and dirt, so this rain is called mud rain.

Why do mud rains occur?

Answer: This rain is a very common phenomenon during the spring and summer seasons. However, it is not limited to these two seasons, but may occur at any time of the year. It is a unique weather phenomenon that characterizes Spain, and the reason for its occurrence is due to African dust, where the Sahara Desert is relatively close to the Iberian Peninsula, which allows strong winds to transport large amounts of this dust to our country, and thus causes this unique type of rain to fall.
When atmospheric dust in the sky acts as a condensation nucleus, it plays an effective role in the formation of rain clouds. This phenomenon occurs due to instability in the atmosphere and fluctuation of the wind. Thanks to these factors, the unique formula of mud rain is completed. When this rain falls, the color of the sky changes, and cars are colored in colors. Muddy and muddy, it's a sight that can't be ignored.

Mud rain in Spain

These rains are sometimes referred to as "blood showers" in some areas, because the mud that deposits can take on a slight red color during the summer and during these rainy periods, the desert and its effect on air quality are much talked about in Spain, as the desert continues to introduce... Dust into the air. The amount of dust that reaches Spain depends on the wind system and its intensity, and these rains can generally be predicted through satellite images.

Rainfall should not be a unique event in areas accustomed to the phenomenon of mud rain. Rather, it can continue for several days, depending on wind conditions and direction. If the instability in the atmosphere, formed by falling clouds and the winds bringing more desert dust, continues, precipitation will be Which are all made of clay.

The areas most affected by mud rain are usually found in Spain, due to its proximity to the African continent, and they can also be seen in the central regions and even in northern Spain, but with less frequency and intensity and the greater the distance, the less likely this phenomenon occurs.

Negative effects of mud rain

The effect of the heavy rain of mud is clearly visible on the roofs of cars , as they become brown in color, and after passing through paths covered in mud, it appears as if they crossed through a swampy area, and the effects of this experience are clearly visible on the car’s body.

But this phenomenon is not limited to vehicles only, its effects can also be seen on sidewalks and even in tree branches. When looking at the sky on those days, it can be observed through the color of the clouds.

These effects are considered a result of the rains that occur in the summer, when the overall temperatures rise, and this happens because the air carried by the desert dust is warmer than the air in the peninsula, which leads to these changes in weather conditions.

When do mud rains occur?

Answer: This phenomenon can occur at any time of the year, but it is more common in the summer and spring. Usually, suspended dust remains in the atmosphere for a period ranging between 24 and 60 hours , then it begins to disappear. It is considered that 70% of the dust present in the world It comes from the Sahara Desert, which is vital information that we must take into account to understand its impact on the ecosystems of the entire planet.

The effects of this mud rain are not limited to our streets and cars, but they also have an impact through their contribution to the nutrition of the soil and oceans, as suspended minerals, bacteria, spores and pollen are transported along with the dust and sand of the southern desert.

Dusty rain gives us the opportunity to explore the mysterious world in our sky, where air, water and particles meet in a magical moment. Understanding its formation and impact opens the doors of exploration to understand the depths of nature, and may reveal to us secrets that constitute the essence of Earth's life.
