What do you mean by the cloud bottom of the weather?

Weather cloud bottom refers to the height of the bottom of the cloud. This is an important parameter in the atmosphere and has an important influence on weather forecast. The height and shape of clouds can be used to forecast the weather. For example, the height of the bottom cloud is lower than1500m, which usually means that it is more likely to rain. Therefore, monitoring the height of cloud bottom can help meteorologists predict the weather more accurately.

The commonly used method is to measure the height of clouds with lidar. The device determines the height of the cloud by sending a laser beam and measuring the return time of the signal. It can accurately measure the height of the cloud bottom and analyze the thickness and shape of the cloud in detail. In addition, there are other methods to measure the height of cloud bottom, such as meteorological instruments and satellite images.

The height of cloud bottom is an important index for meteorologists to predict the weather. The bottom cloud usually cuts off the connection between the ground and the atmosphere, so that the energy on the ground can not be distributed, which leads to the increase of temperature. The height and shape of clouds will also affect the flow of atmospheric airflow, resulting in weather phenomena such as storms and rainfall. Therefore, careful observation of the change of cloud bottom height can help meteorologists predict the weather more accurately.
