Study Suggests Climate Change is Causing More Multi-Day Fog Events in UAE

(MENAFN) A new study conducted by scientists at the Environmental and Geophysical Sciences (ENGEOS) laboratory at Khalifa University in Abu Dhabi has found that climate change is responsible for an increase in the number of multi-day fog events in the UAE. The research also found that the fog that forms during these events tends to be less dense than before, possibly due to urbanization, which has reduced the amount of particulate matter in the air.
The impact of fog events in the UAE, especially during the winter months, is significant, causing significant disruptions in airline schedules and posing hazards on roads. The study, published in the journal Atmospheric Research, analysed data from several decades to highlight how large-scale weather systems outside the region influence fog formation in the Emirates. The research could help forecasters predict when long-lasting fog events will occur.
According to the study, there has been an increase in the frequency of fog events in the UAE, with periods when fog is seen on multiple days becoming more common and lasting longer. However, the events are less intense, and visibility is not hampered as much as before.
The study's head, Dr Diana Francis, explained that the increase in the water vapour content in the atmosphere due to global warming is a possible cause of the increase in fog events.
"We think that the increase [in fog events] can be due to the increase of the water vapour content in the atmosphere due to global warming. We know that a warmer atmosphere can hold a larger amount of water vapour than a colder one," said Dr Francis.
