What the science says: What effect does it have on the weather if it rains in winter? Trending Global News

Winter rains in India: Many parts of India including Delhi NCR are affected by rain. Rain in winter has a different meaning. Fog is likely to increase. Some people believe that it reduces the cold while some people are also found to say that now the severity of the cold will increase. Generally, rain in summer brings relief by first cooling down the hot environment and then also causes an increase in humidity. But what effect does freezing rain have on the weather?

Why does it rain in winter in India??
Rains in India are irregular and infrequent during the winter season. This rain has nothing to do with monsoon. India’s weather is strongly influenced by the northwesterly winds in winter, known as Western Disturbances. These winds come from the Mediterranean in the west. Due to these winds, pressure is created in the atmosphere, which creates the situation of rain.

Effect on temperature
In India, due to the snowfall in the Himalayan regions, the severity of the cold is being felt in the plains. Although the weather is dry in winter, the rainfall in winter also affects the cold weather. It is true that rainfall lowers the local seasonal temperature. Rains cause a drop in temperature and increase humidity in North and Central India. The combined effect of these two increases the cold.

So the cold is not less??
It depends on how cold it already is. For example, if there is rain in the snowy regions, the cold will undoubtedly decrease. Whereas in very cold regions, if the rainwater is relatively cold, it can help to raise the temperature. This is more common in North India, but rarely. Light rain in severe winters can prevent temperatures from dropping too low.

Fog may increase or decrease.
The main effect of rain is to increase fog. In the plains of North India, due to rainfall, the humidity in the air increases greatly, in such a case, if the cold does not subside, the fog can increase significantly. On the other hand, in areas where there is already fog, rain reduces the fog to fog.

Polluted air becomes clean
Also, one of the benefits of rainfall is that it helps reduce pollution and improve air quality in areas like Delhi NCR. In Delhi NCR, winter rains wash pollutants from the air, improving air quality. Especially in cities like Delhi, where smog and pollution increase during the winter season, rainfall can reduce pollution.

Effect on cold wave
Winter rains in North India do not bring cold waves, but when it snows in the Himalayas, it definitely brings cold waves. In such a case, if it rains, it can affect the cold wave to some extent, but it does not end the cold wave.

There is no doubt that rain helps in cooling down the winter season. But it has rarely been seen to reduce cooling. But yes, this rain definitely adds moisture and coolness to the air. Along with this comes the pleasure of reducing polluted air.
