Taya Keating (Member 53,065) spotted Cirrus clouds above Dublin, Ireland that appeared to have been shaped by a perpendicular pattern of wind shear. This pulled them into unusual birdlike shapes. Long, thin strands of cloud with hooked ends caused by wind shear are called Cirrus uncinus. They’re known as ‘mares’ tails’ in maritime circles. When these begin to invade the sky, becoming more and more plentiful over time, they are an indication that a weather front is on its way – one that might eventually result in it ‘raining cats and dogs’. In the meantime, let’s say Taya’s Cirrus sky is ‘blowing birds and horses’.
