Field Trip Post: Number Three

To see a live view of the weather in Roatan, my favorite resort hosts live views of their resort which are updated every 45 seconds and can be viewed here.

Because it is Spring in Roatán, let's simply focus on thunderstorms.

Each thunderstorm has three stages:

Updraft Cumulus Stage

In Photo 1.1, below, you can see the warm air being lifted up v
ertically, which is resulting in large, vertical cumulus cloud formations.

In Photo 1.2, above, warm air has mixed with surrounding seawater, the warm air has risen vertically, which has created cumulus cloud formations.

Mature Stage

In this stage, warm air has risen above the freezing level and co
ndensed. There are strong downdrafts that are pulled down by precipitation. In Photo 2.1, below, moisture has condensed in the clouds on the left part of the picture, and light rainfall is visibly present (shown by the blue arrows).

In Photo 2.2, above, moisture has condensed, many downdrafts have been brought down by precipitation and this has produced a heavy rainfall.

Dissipating Stage

The resultant rain has cooled the surrounding air, and air then flows out of the storm - which creates high winds.

In Photo 3.1, above, the rain has decreased in intensity
, the rainfall has cooled the air surrounding the storm, which has caused strong winds, shown by the trees at the bottom of the photo.

  1. Hi Christian, I really like your pictures and how the arrows show specifically what your readers should be looking at and do a good job demonstrating what you are talking about. I think in the beginning of your blog you should try and put a better attention grabber in though instead of just a picture. Maybe something funny that would relate to your topic.

  2. I like that you include personal photos and have taken an interest in a location that you frequent. The Photoshop arrows really give a good visual aid for the process of thunderstorms. The 200 word restriction makes it challenging to include extra wording, but you definitely have all the form and process! I do the same thing….. but because you have been there I would love to have some personal feedback even if its in caption (as not to off-set the word count) It would make your blog even better and more interesting than it already is!

  3. I really like how you described updraft and downdraft. The pictures help me understand whats going on. I don't feel like they are distracting at all. I feel like I learned more about thunderstorms than I did about Roatan. I would have liked to know why, just because its spring, there are a lot of storms. Great job on the blogs style.

  4. Christian your blog is just well developed. You explained thunderstorms and its processes in a way that made it easy to understand. Your pictures gave me a real feel of what you were talking about. Despite being limited to a word count you described the pictures thoroughly. Not to mention your pictures look original. I would have liked some pictures that showed a sunny day in Roaton, perhaps talked about other clouds.
