One of the most damaging conditions in the aeronautical industry is the formation of fog on the runway, since the consequent reduction in visibility below the corresponding thresholds can generate interruption of operations. In the present work, this fog phenomenon that occurred on May 5, 2021, has been analyzed with data obtained from the METAR (Meteorological Aerodrome Report); Likewise, with the reanalysis information on surface and height levels, it was found that on the surface the atmospheric pressure increases significantly one day before the event and during the event, going from 1023 to 1029 hPa. Likewise, a circulation was identified. high in front of the coast of Lima, favoring subsidence and southerly wind flows, driving the entry of dry air mass. At high levels, the presence of troughs and a highly amplified wave were identified, which promoted the entry of cold air at low levels. In the vertical from the Jorge Chávez airport and the Peruvian sea, the presence of a warm air mass located above the 720 hPa level was identified and by day 04 it fell to 840 hPa, which allowed an inversion at a lower height level; as well as for the day of the evento it descended even more, indicating that the cloud ceilings would also be very low. At the local level, there was the advection of cold and dry air at the surface level, and the increase in subsidence causing the clouds to descend and approach the ground, giving way to the development of fog.
