Look Up – Heavenly Patterns

Evening sky.
In early spring we wait impatiently for blue skies with sunshine, where just a few pretty cotton wool tufts sail along. We are a bit disappointed when grey masses of clouds again gather above our heads. But even with weather like we had yesterday and the day before yesterday there is a chance to look at clouds.
A foggy cloud cover is caused by stratus clouds as well as stratocumulus clouds. All is certainly not just a uniform grey sheet, different air conditions bring different views all the time even on the gloomiest day. In winter the stratocumulus clouds are grey and at a very low altitude – just the height of Munamägi, about 250-300 metres. Low-going, but there is usually no downpour or snow from stratocumulus clouds, only occasionally a little snowslush or rain.
Most often we see in the sky stratocumulus clouds built up from various masses and swathes. Joining together they form dense layers. But the heavenly fog is in a playful mood all the time – between the swathes and banks even clear blue skies look out from time to time. Stratocumulus is the most common basic form of the atmospheric swathes.
Happy watching – the sun now sets after working time and on the way home you have the chance to lose yourself in the colours of the evening skies. Thanks to the clouds each sunset is different.
