Let's analyze what the weather brings us a warm front. Between the appearance of the first clouds and the beginning of the precipitations can happen between 24-48 hours. This means that the predominant clouds are low and medium clouds.Ĭlouds and precipitation develop along the contact surface between the two air masses. That is to say, usually travels at an average speed of about 30 km / h and has a cloud cover height of approximately 7 kilometers. The main feature of the front and warm is that it has a small slope. When air masses collide, condensation and subsequent cloud formation are caused. This lower temperature air mass is known as the cold sector. The hot air tends to rise above the air mass with the lowest temperature. The front and warm are formed when a mass of warm air reaches another of colder air. Depending on the characteristics they have at the boundary of an air mass, we can see the formation of a warm front, a cold front, an occluded front, or a stationary front. That is why we must separate the air masses by a surface of discontinuity.

Warm frontĪs we have already seen, the air mass is characterized by having similar conditions of temperature and humidity throughout it. This turns into an unstable air mass which causes an increase in the intensity of the wind, an improvement in visibility, but a development of clouds and precipitation. It will begin to heat up at its base and they become less dense, which will favor vertical movements. As it circulates on the surface, the opposite effect to the one we have described will occur. On the other hand, if the air mass circulates over a surface that is warmer than it is called a cold air mass.

We also see some difficulties for full visibility and few clouds with vertical development. This stability is a problem for the most polluted cities. This stability stands out for having weak winds, a vertical temperature inversion, which causes an increase in dust from the pollutants that exist in the lower layers. With this type of characteristics, vertical air movements are prevented, thus creating a stable air mass. In this way, as the air on the surface begins to cool becomes denser and heavier. Movement across the surface that has a lower temperature will begin to cool down the part closest to the ground. If an air mass circulates over a surface that is cooler, it is considered a warm air mass. These situations are associated with depressions since there is a drop in atmospheric pressure and the creation of a storm. On the other hand, when there is unstable air, we see that vertical movements are favored and rain clouds are produced with rough weather. When there is atmospheric stability, it is very appropriate to speak of anticyclones. For this reason, the formation of precipitation clouds cannot occur. When we have a stable air we speak of an area where movements are not allowed vertically. The stability of all air masses is what determines the weather that occurs in a certain area. To understand what a warm front is, we must know the atmospheric dynamics in relation to the functioning of the air masses.
