Why is it bright on a cloudy day?

The sunlight itself is not at all brighter or hotter. The surrounding clouds play no role in how the direct sunlight affects the ground level environment. If that were so, then an entirely cloudy day would be hotter and brighter than a cloud-free day.

Why do I like cloudy rainy days?

For them, cloudy days are not only respite from the heat but they also bring a change in the scenery and break the monotony, which in return has a positive effect on the person’s mental psyche. Same way sunny days effect people living in cold or wet climates. Another reason could be a person’s personality.

Is there sunlight on rainy days?

Even on rainy days, solar panels generate electricity due to visible sunlight coming through the rain. Solar panels work more effectively after rain because the water washes away any dirt, dust, or pollen. The MIT scientists discovered that dust can reduce the efficiency of the solar system by 12 – 17 percent.

How bright is a cloudy day?

Over 40 times brighter than what is being specified in most office spaces today. Even an overcast and cloudy day can easily be over 1,000 foot candles (10,000 lux).

Can clouds make the sun brighter?

Clouds Gone Wild The second component accounts for the sunlight scattered between and under clouds, which makes the sky brighter, warming Earth. “The sunlight scattered by clouds can heat the surface,” said Kassianov. “We all know that we can still get sunburned on cloudy days.

Why is the sky bright at night when it rains?

The luminosity of the night sky seems to be magnified after rains, i.e., when there is cloud cover in the sky. The reddish hue that you see at sunset (especially during rainy seasons) is due to the reflection of light from the low-cloud base, which happens to be relatively close to the ground.

What is the light intensity of sunlight?

At Earth’s average distance from the Sun (about 150 million kilometers), the average intensity of solar energy reaching the top of the atmosphere directly facing the Sun is about 1,360 watts per square meter, according to measurements made by the most recent NASA satellite missions.

How do clouds reflect sunlight?

Clouds cool the Earth by reflecting incoming sunlight. The tiny drops or ice particles in clouds scatter between 20 and 90 percent of the sunlight that strikes them, giving them their bright, white appearance. From space, clouds look bright whereas large bodies of water look dark.

How do clouds affect sunshine?

Clouds can block light and heat from the Sun, making Earth’s temperature cooler. Well, that depends on where the clouds are in Earth’s atmosphere. Clouds within a mile or so of Earth’s surface tend to cool more than they warm. These low, thicker clouds mostly reflect the Sun’s heat.

Why is it cooler on cloudy days than on sunny days?

This process is called evaporation. This water vapor rises upwards. It cools to form clouds. When the skies are full of clouds, the weather is said to be cloudy. Only some dark clouds bring rain. On cloudy days, the rays of the sun cannot reach the land. Thus, the weather is cooler on cloudy days than on sunny days.
