MARTA MORTON—WWW.HARBOURCLUBVILLAS.COM Above: These cloud images were shot overlooking Flamingo Lake in Providenciales. Below: This image of an Arcus shelf cloud was captured from the deck at Harbour Club Villas. Note the characteristic rising cloud motion in the leading part, while the underside appears turbulent. But how do these clouds form, and why do they tend to form over some of the same areas day after day across the Islands? To understand how this happens, we need to first understand the “whats” (atmosphere and geography requirements) before we get into the “hows” (actual formation of clouds), and the “when” (likely times to see these clouds form). Let’s take a look at the “whats” first. The Turks & Caicos Islands are completely surrounded by the Atlantic Ocean. In general, high pressure exists over areas that are cooler (water) than adjacent areas (land). Low pressure generally exists over the warmest areas (land) surrounded by cooler areas (water). For the TCI, the waters in general are cooler than the land mass during the day, while at night the water generally is a bit warmer than the land. So during the day, low pressure typically exists over the Islands (rising air), and at night, high pressure is usually situated over the Islands (sinking air). This scenario plays out during calmer weather periods. It is also important to understand that winds will gen- MICHAEL MORTON—WWW.HARBOURCLUBVILLAS.COM 14 www.timespub.tc
This image explains the concepts of sea breeze and cloud formation. erally blow from high pressure towards lower pressure, which during the day is from the ocean to the land. At night, we normally see the reverse situation—winds blowing from land out to sea. One final factor that will play into cloud formation has to do with the amount of moisture in the air. And we know based on geographic location that there is an abundance of moisture in the atmosphere generally at all times over the Islands. Now let’s discuss the “hows” of cloud formation. Clouds are a conglomeration of trillions and trillions of molecules of water vapor. Generally unseen to the naked eye, yet felt on the skin as humidity, water vapor once compacted into large areas reveals itself as clouds. How is it we see these clouds? In the Caribbean, we can thank the salt in the ocean for this! In order to see clouds, we depend on what is called Cloud Condensation Nuclei, abbreviated as CCN. These are particles of dust, salt, pollution, and even sand from the Saharan Desert. Water vapor by nature, will need something to condense to in order for us to see it visibly. These CCN stick to water vapor, which is the single most important item we need for cloud formation. For the Islands, salt water evaporates off the surface of the ocean and rises into the air as the CCN needed. However in order to see these as clouds we need something else to occur. During the day, as the land heats up and low pressure develops over the land, the warm air rises in convective currents off the hot ground into the air above the Islands. As the winds blow off the water and arrive on land, they get naturally deflected up as they encounter topography and the much warmer air that is also rising. As this wind and air rises, it naturally begins to cool once again. And as that air cools, it also condenses. Those trillions of molecules of water vapor become visible as tiny water droplets. And in mass, they are visible as the fluffy white clouds we see across the Islands. If you would like to see this in action on a smaller scale, boil a pot of water on the stove.
