 Above is a satellite image taken of Haiti, with a market over Port-au-Prince. Grey and white shaded areas represent low, warm clouds whilst blue clouds represent high, cold clouds. Coming in from the Dominican Republic are high clouds. There are situated in the North-East part of Haiti. Low, warm clouds are lightly scattered throughout the country: some are located in the center of the island nation, while others are resting over South-Eastern coast.

This next image is a satellite image of Port-au-Prince. To be quite honest, I'm not sure if there are thin, low warm clouds over the capital or if there is heavy pollution, as Port-au-Prince and its surrounding neighborhoods are densely populated. The green areas on the map represent forests. 

Regional (Synoptic) Patterns of Low and High Pressure and Fronts:

Above is a map of the Caribbean. Observed isobar pressures are: 1016 mb over Florida, 1016 mb North East of the Hispaniola and Porto Rico, and 1012 mb off of the coast of Central America. High and Low pressures are not present of this particular map. A cold front located over Cuba from Florida moves toward Hispaniola.

On the larger map of the Continental US, several low and high pressure areas are present. In respect to the Caribbean region, there is a high in the Gulf of Mexico near Louisiana and Florida, and a Low off the coast off of Virginia and North Carolina. Also, there is a high present over North Carolina. The Cold front over Cuba is a part of a mid-latitude cyclone (the center of which is the low off of the coast of Virginia and North Carolina). Another mid-latitude cyclone is approaching the end of its "life" over Kansas and Missouri.

Global and local winds in Haiti

Location and Global Wind:
Haiti is located at a latitude of 19° 00' N and a longitude 72° 25' W (Maps of the World). Therefore, the island nation is located in both Northern and Western hemispheres (worldatlas), and resides within the Hadley cell. Due to the fact that Haiti is located towards the middle of the Hadley cell, the nation is located south of the Horse latitudes and north of the Equator, receiving north-easterly trade winds (click here for a visual representation). Besides the north-easterly trade winds, Haiti experiences winds from other directions. From April to June, the prevailing winds are from the Northeast. Winds from October to November are from the Northwest (Woods, C.). Haiti is located south of the subtropical high and north of the ITCZ, a low pressure zone (click here for a visual). Haiti is not located near either of the pressure belts: Haiti is located at a latitude of 19° 00' N, while the ITCZ is located at a latitude of 5° 00' N/S (geography.about.com) , and the subtropical high pressure belt is located at the latitude of 30° 00' N. Therefore, one could argue that Haiti is located slightly closer to the subtropical high pressure belt than the ITCZ. Another important factor to note is that Haiti is in-between the Horse latitudes (30° 00' N) and the doldrums (0° 00', or the Equator).  While Haiti's geographic position is somewhat closer to the Northern Horse latitude than to the doldrums, Haiti is not as affected by these two special forces as other areas (such as Florida or French Guiana) are.

Global Wind and Weather:

As previously stated, Haiti lies towards the center of the Northern Hadley cell. Due to its distance from the Equator and Sub-tropical high, Haiti experiences a warm, tropical, humid climate with high rates of precipitation. Separation from the polar fronts prevents Haiti from experiencing seasonality like other nations located within the mid-latitude cells. Seasons, therefore, are mild. Trade winds help to regulate Haiti's climate, bringing cool air from the north-east over Hispaniola. Rain shadows exist in Haiti due to orographic lifting on the leeward side of the island, which is a part of the Dominican Republic (Woods, C.).  Hispaniola's position within the Hadley cell and distance from the Equator and Sub-tropical high also affects its weather. Precipitation that occurs within the area is rain, formed mainly by the collision-coalescence process. Tropical storms can also effect the area, as such storms form over the warm tropical waters of the region.

Local Winds:
Topographic characteristics determine the types of local winds experienced in a geographical area. In Haiti, there are three main mountain regions, with two minor ranges and a lone peak. In northern Haiti lies the Chaine du Haut Piton; the Massif de la Selle runs southeast of the capital, Port au Prince. The southwestern end of the nation features the Massif de la Hotte. Two other mountain ranges, the Massif des Montagnes Noires and Chaine des Cahos, also are present in Haiti, as well as the lone mountain Montagne Terrible (Maps of the World). Winds or breezes have been associated with mountain ranges worldwide. Five types of breezes or winds are associated with mountains: Katabatic winds, Chinook or Foehn winds, valley breeze, mountain breeze, and Santa Ana winds. Haiti can and does experience several of these winds. Valley and mountain breezes can form in any area with valley walls. Haiti does also experience the effects of Chinnok winds,as Haiti part of Haiti is in the rain shadow of the Dominican Republic. The island nation does not experience Santa Ana winds or Katabatic winds: these types of winds are dependent on a geographic location (near a desert or near an Arctic tundra) that do not exist in Haiti. While topography can generate local winds experienced in an area,  being located near a body of water can also generate local winds as well. Haiti's coastline borders with the Atlantic Ocean in the North, the Windward Passage to the east, and the Caribbean Sea to the south(Maps of the World). Two types of local breezes are associated with coastlines: sea breeze and land breeze. Haiti can and does experience both types of breezes, due to the fact that Haiti is partially surrounded by the ocean.
