Frontal Zone

This photo shows an extensive and a clear-cut cloud formation clearly representing the rear edge of a developing cold front signalling the end of bad weather and progressively clearing skies from the west. The cloud band is likely to have been as wide as the cold front itself stretching for several kilometers. For a detailed explanation of the prevailing weather situation, kindly click here. The main photo depicts at least three different cloud formations being altocumulus, cirrus and stratus. This may be a rare weather photo for the Maltese Islands in the sense that the cold front edge was clearly observed at ground level in the form of stratus fractus clouds gliding over the ground which rises up to 250 metres above sea level. This explanation is illustrated through a small video on the third thumbnail showing the creating and dissipation of low clouds including a panoramic photo depicting the fuller scenery. It is not known if the low clouds have persisted longer due to falling darkness. The stratus cloud height was certainly lower than 180 metres as per MIA reading on the seventh thumbnail. On the other hand, the upper-level clouds illuminated by the setting sun, seemed to have been composed of altocumulus stratiformis opacus with hints of undulatus and mammatus. The former variety created by lots of wind shear as per weather sounding on the fifth thumbnail whilst the latter variety would have been the result of a descending airmass in parts following the cold front. Thin cirrus clouds were also visible. The first and second thumbnail photos depict the continuous changing scenery as sunset progressed on both the cloud levels particularly low stratus which by nature undergoes continuous change in shape and form as the wind acts upon it. Contribution to this explanation is always strongly encouraged.
