When the cold front moves faster than the warm front, and as it overtakes the warm front, the warm sector is closed and a combine front forms. This process is called occlusion. The front formed in this way is called an occluded front. 4, record 1, English, - occluded%20front

... a neutral occlusion, results when there is no appreciable temperature difference between the cold air masses of the cold and warm fronts. In this case frontal characteristics at the earth's surface consist mainly of a pressure trough, a wind-shift line, and a band of cloudiness and precipitation. 2, record 2, English, - neutral%20occlusion

Le terme «occlusion» est utilisé pour désigner la structure frontale qui se développe lorsqu'une masse d’air froid qui s’avance rejoint une masse d’air froid qui s’éloigne; en d’autres termes, le phénomène qui se produit lorsqu'un front froid rejoint un front chaud. Pour étudier ce phénomène nous devons tenir compte des températures de trois masses d’air : l'air froid antérieur, l'air chaud et l'air froid postérieur. [...] Occlusion neutre. Dans certains cas, il n’ est pas possible de différencier les masses d’air antérieur et postérieur. On parle alors d’occlusion neutre. Dans ces cas, on a simplement occlusion et la projection de la vallée chaude se représente par un trait violet ou par des demi-cercles et des triangles blancs alternés et dirigés dans le sens du déplacement de l'occlusion. 1, record 2, French, - occlusion%20neutre
