These latitudes are often called Roaring Forties, Furious Fifties, and Shrieking Sixties – dreaded terms for sailors.The poleward boundary of the westerlies is highly fluctuating. There are many seasonal and short-term fluctuations. These winds produce wet spells and variability in weather. pallavia https://padlet.com/pallavia/winds/wish/210104068 2017-11-26 06:42:40 UTC https://padlet.com/pallavia/winds/wish/210104068 LOCAL WINDS pallavia https://padlet.com/pallavia/winds/wish/210106611 2017-11-26 07:30:35 UTC https://padlet.com/pallavia/winds/wish/210106611 MONSOON WINDS pallavia https://padlet.com/pallavia/winds/wish/210106695 2017-11-26 07:32:30 UTC https://padlet.com/pallavia/winds/wish/210106695 KATABATIC WINDS pallavia https://padlet.com/pallavia/winds/wish/210108336 2017-11-26 08:04:48 UTC https://padlet.com/pallavia/winds/wish/210108336
