This week’s image was taken this morning over Texas. Finally, I posted one that is not a tropical system.
The image above shows cloud streets streaming into eastern Texas from off the Gulf of Mexico. It demonstrates the difference between cloud streets and mountain wave pattern (cloud streets point to their moisture source, mountain wave pattern clouds run parallel to the mountains, perpendicular to the wind direction). It also shows the effects of rising topography and the sea breeze. Notice how the clouds start a little ways inland, and even though there is almost the same air mass over the Gulf, there are few clouds and no cloud streets. As the moisture is advected inland, it rises with the topography and forms the clouds over land, but not as many over the sea.
Thank you for reading this post!
