What type of weather front is represented by triangles and semi-circles on the same side?

The scenario described in the question, where triangles and semi-circles are depicted on the same side of a front, corresponds to an occluded front. In meteorology, an occluded front occurs when a cold front overtakes a warm front, causing the warm air mass to be lifted off the ground.

This front is characterized by its mixed symbols: triangles represent colder air descending behind a cold front, while semi-circles indicate warmer air associated with a warm front. The combination of both symbols on the same side signifies that the front is in a transition phase, where the cooler, denser air has lifted the warmer air aloft, creating a complex interaction resulting in changeable weather conditions typically found in the vicinity of occluded fronts.

Understanding the characteristics of an occluded front helps in predicting weather patterns effectively, as it often leads to cloud formation and precipitation, contributing to a better analysis of atmospheric dynamics.
