What do you mean by low clouds?

Low clouds mean high air pressure, the airflow on the ground and in the air is different, and the water vapor content in the air is high, which is a precursor to rain. In addition, the height of cloud formation, called uplift condensation height, can be estimated by the temperature drop rate and dew point temperature drop rate during dry adiabatic process, which is usually determined by temperature (vertical profile) and water vapor content.
