Weather - What is a Warm Front?
Answering what is a warm front depends on knowing cold fronts. Under general circumstances warm air cannot displace a mass of cold air. Masses of cold air are often called cold fronts and are often denser than warm air. Since the two types of air have distinct densities and temperatures, they also cannot mix. What normally happens when there is a cold front is that warm air is displaced and moves over the cold air. This is because warm air is lighter. Once there, warm air will grow cooler and form into clouds.

In some cases, cold fronts will not cause any considerable weather changes. If there is enough moisture however, cold fronts can lead to rain showers and thunderstorms that can last for weeks. Severe storms can even be accompanied by floods and tornadoes. Floods in singular do not fast dissipate because cold fronts take some time to pass through.
So what is a warm front? They are simply what cold fronts are not. Warm fronts are the front portions of warm masses of air that move in to replace preceding cool air. As expected, air in front of the warm air mass is cooler than air behind warm fronts. In weather maps, it is represented by solid lines with semi circles or rounded lumps attached to the front of the lines. This is opposed to solid lines with pointed triangles that recite cold fronts.
Unlike cold fronts, warm fronts are not typically linked with devastation. This and other warm air mass conditions put warm fronts in stark unlikeness to cold fronts. The following are what you would expect when a warm air mass approaches or passes:
o Temperature conditions while warm fronts are opposite of that while cold fronts. Before a warm front passes, the temperature is noticeably cooler. If you are directly in line as a warm air mass passes, you will notice a quick convert in temperature towards warmer levels.
o Cold fronts may lead to strong showers. Warm fronts any way are typically accompanied only by light showers and drizzling especially as the warm front passes. Despite the drizzle though, surroundings can still feel more humid.
o Winds in the southern hemisphere will blow north to northeast. Those in the northern hemisphere will blow south to southeast. As the warm air mass passes, the direction of the winds will shift.
o Visibility as a warm front passes will be poor and hazy. Sometimes, fog can also form near the ground.
o Atmospheric pressure while the duct of warm fronts will fall and then rise and then fall again after it passes.
