This is a warm front. They occur when a warmer air masses tries to push into a cooler, drier air mass. It has to ride up and over the cooler air, "squeezing" it out rather than wedging it upward from below. Precipitation along this boundary is usually much gentler than that along a cold front, but can last much longer. Rather than the clear, crisp air that follows a cold front, hazy or muggy conditions can follow a warm front.
a warm front
When a cold air mass moves into an area where a warm air mass is located, it is called a cold front. Cold fronts typically bring cooler temperatures, precipitation, and sometimes thunderstorms as the denser cold air displaces the warmer air.
Cold front
Cold fronts often bring rain because as the denser cold air mass moves into an area, it displaces the warmer air and forces it to rise rapidly. This rising warm air cools and condenses, resulting in cloud formation and precipitation. The intensity of the rain can vary depending on the moisture available in the air.
When a warm front moves into a cold front, the warm air gradually rises over the denser cold air. This can lead to the formation of clouds and precipitation. The warm air displaces the cold air, leading to a gradual increase in temperature and humidity.
then condensation will occur
Under these conditions the cold front will probably bring thunderstorms.
Shanghai has a humid subtropical climate.
When cold air moves into an area, the atmospheric pressure is high because cold air is denser than warm air. When a cold front moves through an area, the pressure always rises.
Cold
Winds become gusty;there is a sudden drop in temperature and heavey rain,sometimes with hail,thunder and lightning
The temperature decreases.
Yes, it is possible for a region to be both cold and humid.
it is called a cold front
Animals that live in humid cold areas include polar bears, Arctic foxes, reindeer, and snowshoe hares. These animals are adapted to cold temperatures and often have thick fur or layers of fat to help them survive in these environments.
It would be a cold-front
