Flying saucer-shaped clouds form over southern Vietnam mountain again

Residents in the southern Vietnamese province of Tay Ninh on Saturday morning once again saw flying saucer-shaped clouds float above Ba Den Mountain.
A similar natural phenomenon was seen atop the mountain in November last year.
Locals said the mountain looked like donning a white hat at about 6:00 am.
Many of them excitedly took photos of the spectacular moment.
The phenomenon is known as lenticular clouds, which are caused by sudden air movements and often found near hills or mountains.

| The phenomenon is also seen atop Mount Fuji in Japan, Mayon Volcano in the Philippines, and Etna Mountain in Italy. |
As moist and stable air flow over a larger eddy, like those caused by mountains, and temperatures drop below the dew point, lenticular clouds can form.
Lenticular clouds in the shape of a flying saucer are special and infrequent, according to Le Dinh Quyet, deputy head of the forecasting department at the Southern Center for Hydro-meteorological Forecasting.
Standing at 986 meters above sea level, Ba Den Mountain in Tay Ninh Province has been dubbed the 'roof of Vietnam’s southern region.'

| Lenticular clouds once covered the peak of Ba Den Mountain in Tay Ninh Province, southern Vietnam in November 2022. |
|
|
| The temperature in the mountain during the occurrence of lenticular clouds is over 10 degrees Celsius lower than normal. |
