There are several types of clouds that the scholars can tell you about or that you can study from the internet. In this space I am only going to talk about how it relates to travel. Travel by air, land or sea exposes you to some great clouds and it sets the mood for your vacation.
Cumulus cloud : best sunny beautiful, feels good, usually seen upon arriving the Caribbean, beach, and pool side. At this point you simply begin to enjoy your trip.
Cumulonimbus : beauty over ocean type. Again, this cloud brings joy and imagination of fun activities in any given location.
Cirrostratus: blue ocean type that hovers over the seas exposing the crisp blue waters that simply soothes the soul. Your happy place in the clouds as you close your eyes and just relax.
Altostratus cloud: dull, rain is coming, not good for arrival if in the air. On a location, you might want to plan for indoor activity. This cloud is not all bad, look out for the rainbow that it brings to brighten your day.
Stratus: overcast, dark, rain, possible tornado in the horizon. Recipe for a not so great trip. With the right attitude , you can still pull off a great day.
