VARIATION IN FOG INTENSITY/DURATION AND EL NINO

Syed Faisal Saeed, Asma Younas

Abstract


The intensity and duration of Fog over the plains of Punjab has been seen to significantly vary during the past decade. Fog is one of the climatic parameters in the region and appears normally for very short durations of few hours. This figure, it has been seen, crossed 300 hours during the El Nino year of 1997-98. The study conducted in this regard revealed that during El- Nino years, the pressure over the region rises. A correlation of 80% was found to exist between the pressure of Darwin and the upper Punjab and this higher pressure increased stability over the region that creates an atmosphere conducive for the formation of Fog for longer duration in winter season.
