Did you notice that the pictures of marshmallow-shaped clouds on your Facebook timeline yesterday? The dreamy scenes were mostly captured in northern Taiwan in the afternoon.
But, what is the reason for this beautiful scenery? The marshmallow-shaped clouds belong to the family of Altocumulus clouds, which usually appear in layers or patches. The Altocumulus clouds are formed by convection in an unstable layer aloft.
Besides, the presence of the Altocumulus clouds is generally followed by changes in weather on the next day, according to the deputy director of the Central Weather Bureau (CWB).
As the northeast monsoon strengthens, the temperature drops in the northern and northeastern Taiwan, with the lowest temperature dipping to 18 degrees Celsius on Nov. 25.
