Why is the weather still cloudy today?

1. From the clouds

1. Cloudy days: The total cloud cover of low clouds in the sky is 8/10 or above, and the clouds are usually gray or black, which is lighter than ordinary clouds. The case should be thicker.

2. Cloudy: a weather phenomenon in which low cloud cover accounts for 4/10-7/10 of the sky area or high cloud cover accounts for 6/10-10/10 of the sky area.

2. In terms of the intensity of sunlight

1. Cloudy day: a sky condition in which little or no sunlight penetrates the clouds and the sky is dark.

2. Cloudy: There is not enough sunshine, but you can still see sunny days through the gaps in the clouds. It refers to a kind of weather that can be called "between sunny and cloudy".

Pay attention to the issue of collapse

Be careful of ultraviolet rays during activities in cloudy weather. Ultraviolet rays are a general term for radiation with wavelengths from 10 nanometers to 400 nanometers in the electromagnetic spectrum. They are invisible to the human eye, but too much ultraviolet rays may damage the eyes.

The German Good Vision Association reminds that people should not forget to protect their sensitive eyes on cloudy summer days, because some ultraviolet rays can still pass through the clouds and reach the surface, exposing the eyes to these for a long time. Under ultraviolet rays, it is likely to cause some damage.

The association also said that because the water surface reflects light, people who stay near the water for a long time should pay more attention to protecting their eyes and clothing. If your eyes are exposed to too much UV rays, symptoms such as redness, swelling, tearing, and eye muscle tension may occur.

The weather forecasts from weather stations are becoming increasingly inaccurate, which may be caused by multiple factors. The following are some possible reasons:
1. The complexity and variability of the weather itself: The weather is very complex and changing. Even if the weather station uses the most advanced meteorological equipment and algorithms, it is difficult to accurately pre dict each event. Specific weather conditions in the area.
2. Climate change: The impact of global climate change on weather is becoming more and more obvious, such as the melting of polar glaciers and the rise in ocean temperatures. These will affect the weather changes and make pre dictions more difficult.
3. Forecast error: The forecast error of the meteorological station may also lead to inaccurate forecasts. Forecast errors may come from limitations of meteorological models, data errors, human factors, etc.
4. Delay effect: Weather forecasts are usually derived based on meteorological models, and changes in meteorological models take time, so there may be a certain delay in weather forecasts, which may also lead to inaccurate forecasts.
In short, the weather forecast of the Meteorological Observatory is not completely accurate, but the Meteorological Observatory will continue to improve its technology and models to improve the accuracy and reliability of the forecast as much as possible. At the same time, we can also better understand the weather changes and pre ventive measures by observing weather changes and analysis by meteorological experts.

Hello, the poster is happy to answer your question:

In the weather forecast, cloudy means that the clouds in the sky are thicker and thicker. Not much, the sun is not very bright, but you can still see the blue sky through the gaps in the clouds. A weather phenomenon in which total cloud cover accounts for 2/10-8/10 of the sky area.

Weather forecast cannot determine the exact weather in an area very accurately. It can only roughly determine the general weather in an area. The clouds in the same area may be different. There are many places with meganano clouds, and some places have less. It's just like the weather forecast says it will rain in Beijing, but it may rain in some places in Beijing and not rain in other places.
