Clouds formed as a result of convection in the atmosphere. Cumulus, cumulonimbus, and altocumulus clouds are examples of convective clouds.

There's an increase in the amount of clouds, with a chance of convective clouds amassing over the western and eastern areas by the afternoon," he said.
According to the observations and advisory issued by the National Multi Hazard Early Warning Center, Directorate General of Meteorology at the Public Authority of Civil Aviation (PACA), Ashobaa is approximately 160 kilometers from the South Al Sharqiya coast with surface wind speed between 30 to 40 knots (56 -- 74 km/h) with convective clouds around 60 kilometers from the coast.
The NCMS said fresh winds associated with convective clouds affecting the island, coastal and western areas kicked up dust, reducing horizontal visibility.
These findings explain the increase in wintertime convective clouds that researchers have observed in this region (using satellite measurements) since the 1990s.
In a statement released on Tuesday, the NCMS said it expected weather conditions for Wednesday to be dusty and partly cloudy in general: "The amount of clouds increases over some regions, especially the northern, eastern and the islands, with probability of convective clouds accumulation over the eastern mountainous region by afternoon.
The weather conditions followed a pretty standard pattern of being clear in the morning but then gradually clouding over as convective clouds formed.
Convective clouds can build and collapse surprisingly quickly; in 2012, above a fire that raged on the border between Arizona and New Mexico, columns of clouds built and collapsed several times within about three hours.
PACA said, in a statement today, that the advection of convective clouds associated with varying heavy rains, sometimes thunderstorms, is expected on the coastal areas of the Governorates of the South A'Sharqiyah, the Al Wusta and Dhofar starting from this evening till the end of this week.
In particular, they were working to understand how the convective clouds -- updrafts that cause storms to build high into the sky -- contribute to the creation of cirrus clouds.
Called deep convective clouds, thunderstorm clouds reflect a lot of the sun's energy back into space, trap heat that rises from the surface, and return evaporated water back to the surface as rain, making them an important part of the climate cycle.
The Deep Convective Clouds and Chemistry (DC3) field campaign is using an airport in Salina, Kan.
In this preliminary study, a compromise has been made to examine the effects of a warmer, moister atmosphere on the products of the warm rain process in deep convective clouds by using a very simplified treatment of the air motions within such clouds.
