Qatar Meteorology Department (QMD) warned people about severe storms associated with strong winds, poor visibility at some places in the country in its weather report on Tuesday, 29. September 2020.
QMD mentioned that local cloud development was observed in some regions with a chance of isolated storms on Tuesday and Wednesday 29.-30. September 2020.
Little country in Persian Gulf really hit storms, which were surprisingly locally severe.
Cooldown from +42°C to +38°C (maximum temperature for 2 days) in Qatar capital Doha, severe storms and dust storms with rarely tornadoes has appeared in country at the end of September – the month, with average monthly precipitation amounts 0,0 mm. In October, precipitation are more frequent, with monthly average 0,1 mm of rain.
The most of rain fall in country during the winter, from 1 to 2 mm in average, with yearly precipitation totals around 8,8 mm.
Recent storms should be linked with anomalous southern shift of jet-stream and AO- (negative phase of Arctic oscillation), such as with climate change. During the autumn (and early winter), thanks to extremely melted Arctic, jet-stream and stormtracks of cyclones are shifting to more southern areas than was usual in the 20.th century. A results of this anomalous circulation are unexpected storms, winds or rainfalls in the areas where winter circulation patterns of weather were coming predominantly mainly during winter months, such is Persian Gulf region or some parts of Sahara.
