Global and Local Winds in Costa Rica

     Costa Rica is located in the Northern Hemisphere and lies between latitudes ranging from 8 degrees North to 11.04 degrees North, and longitudes ranging from 82.36 degrees West to 85.56 degrees West. In respect to atmospheric cells, Costa Rica is situated in the Hadley Cell. This cell ranges from the equator to about 30 degrees in latitude, which places Costa Rica well in that range. The wind belt in which Costa Rica is located is the Northeasterly Trade Winds, meaning the winds are coming from the Northeast and blowing towards the West. These trade winds occur right at or near the equator in both the Northern and Southern Hemispheres. Costa Rica is also located near a low main pressure belt, which runs along the equator. It is also located near a “special” area known as the Doldrums, where the trade winds from the Northern Hemisphere meet the trade winds from the Southern Hemisphere.

     As I mentioned earlier, Costa Rica is located in the Hadley Cell, very close to the equator around the 8-11 degrees North latitude range. Due to it being surrounded by water on the east and west and the winds coming from the east, the west side of the country tends to be drier due to the mountains stopping a majority of the water (in the form of clouds) that it blown in from the east. The fact that Costa Rica is located so close to the equator keeps the climate nice and warm, while the trade winds cool it down and make it bearable to live in around a comfortable 70-80 degrees.

     Costa Rica is a country that consists of a few mountains and a few more volcanoes. Five types of winds that could be associated with these elevated formations could be mountain breezes, valley breezes, Eddies, Chinook winds (associated primarily with the Rocky Mountains), and Katabatic winds. Out of these five, Costa Rica experiences mountain breezes and valley breezes along with occasional Eddies. These breezes flow up or down the mountains and volcanoes, depending on the breeze, and tend to keep the valley a nice moderate temperature throughout the year. Along with the mountains and volcanoes, the country is surrounded by water on both sides giving it two coastlines. The two breezes associated with these coastlines are sea breezes and land breezes and Costa Rica experiences both of them.

  1. My country of Zimbabwe is located within the hadley cell as well. Albeit, the southern hemisphere Hadley cell. This makes our trade winds almost the mirror images of each other with yours coming from the Northeast and mine coming from the Southwest. Zimbabwe unfortunately has no coastline, so the only winds we really have in common are the valley and mountain breezes. Your climate must be wetter because you are in the area where the warm moist air rises in the Hadley cell. Zimbabwe is actually almost right in the middle of the cell, which means less precipitation comparatively.

  2. Hi Robert!
    I think it's cool knowing the weather and climate in Costa Rica and how you supported it with the things we learned in class about winds. I didn't know that one side of the country is drier than the other because of the mountains affecting the winds. Our countries seem to have some similarities and differences though which I also find interesting. Unlike Costa Rica, Tanzania is located in the Southern Hemisphere just below the equator. A similarity our country have is that they are both located in the Hadley cell, although different hemispheres. Your post was really interesting though!

  3. New Zealand is pretty opposite of Costa Rica! We are in the Southern Hemisphere and in the Ferrel Cell where we aredominated by prevailing westerlies. Since New Zealands an Island with Mountains too we still get similar breezes and winds!
