In 2019, on this day in @weather_history #Hurricane Barry made landfall in #Louisiana. It was a unique storm because part of its origin was over land, before developing in the Gulf. youtube.com/watch?v=2_hi9z…
Yesterday in #NewHampshire, the principal of rising air, cooling, and becoming saturated on display, as air flows over mountains. On the downwind side, sinking air warms and relative humidity falls so that the clouds dissipate.

Aside from waves on the water, we can get visible waves in our atmosphere called Kevin-Helmholtz clouds. When the air’s upper layer winds move at faster speeds than the layer below it, it can cause the cloud tops to spill over like that of a breaking wave. #flwx
