Will it rain today?

It will rain today. Because rivers, lakes and oceans are irradiated by the sun, the water inside becomes steam. Water vapor rises into small water droplets and finally becomes clouds. Small water droplets and small ice crystals in the cloud collide with each other in motion, thus increasing the volume. Then, after the ice crystals in the upper layer of the cloud slowly increase in volume, they fall between the water droplets in the lower layer of the cloud, and the water droplets will become bigger and bigger. When these water droplets are too big for the updraft to contain them, it will rain.

Rainproof measures

1. When it rains, the most slippery road surface is not after the heavy rain, but just after the rain, the dust and oil on the ground begin to loosen, and a slippery mixture of oil and sludge will form on the road surface. So, when it starts to rain, don't accelerate, be more cautious and slow down.

2. It's dangerous to press the thread. Driving in rainy days, the white lane lines, various turning signs and crossing lines on urban roads are more likely to slip after the wheels are pressed.

3. Pay special attention to roads similar to road signs when going to the underground garage. Now many underground garages are painted with green paint or other materials. The ground is as dangerous as an ice rink after being wet by the tires of the previous vehicles.

4. Pay attention to the joints at the corner of the elevated road. Joints of elevated roads are usually smooth metal surfaces. In rainy days, when the vehicle passes through the joint on the curve, the vehicle will be thrown out unconsciously. At this time, the driver is required to slow down and hold the steering wheel with both hands to pass safely.

5. Be careful when crossing the wading section. When passing through the wading section, it is recommended that you judge whether to enter according to the vehicle condition and your own driving skills, and do not blindly enter the water accumulation area or quickly pass through the water accumulation area.
