A Katabatic Wind

grey sunless morn, smothering sadness pent up for reasons not known to me … now flows down like a katabatic wind cold and dry, in an inundating landslide. Sun shouts through the hills. Note: A katabatic wind (named from Ancient Greek katábasis meaning 'descent', also spelt as ‘catabatic') is a drainage wind, a wind that carries high-density air from a higher elevation down a slope under the force of gravity. Such winds are sometimes also called "fall winds". Katabatic winds can rush down elevated slopes at hurricane speeds, but most are not that intense.
