1. What are the effects of airflow and convection, and what kind of weather will it form? 2. What is a thunderstorm? 3. What is frontal water vapor condensation?

1. Convection of airflow will form convective rain, but it must be cold and warm airflow. 2. I don't know about the thunderstorm. 3. When the cold and warm air masses meet, the warm air mass climbs, and the water vapor condenses before the warm front to form rainfall. When the warm air gets cold, the air sinks to form rain. Warm and humid air flow forms plum rain in the middle and lower reaches of the Yangtze River. 5. Cyclones are low pressure, and the air sinks to form rainfall. Rainstorms form in tropical and subtropical summers, and typhoons are also cyclones.
