The knowledge of the climatic dynamics and its behavior in a specific region is an implicit requirement for the development and progress of the region itself. Though there exists meteorological and oceanographic information of the pacific Colombian littoral, in the present research has been determined specifically the principal atmospheric variables presented in Tumaco Bay. Some variables have been monitoring for more than 50 years, and based on Principal Climatological Stations, Satellite Automatic Weather Stations and directional wave buoys' data collections. Climatological averages of temperature, relative humidity, atmospheric pressure and precipitation have been calculated. Additionally, it was carried out a monthly characterization of the wind's speed and a wave's direction analysis. These results set a framework that involve seasonal variability defining the wet season in the first half of the year and semi-wet season in the second, with an average of 200 mm per month. The Oceanic Niño Index (ONI) does not clearly represent the effect of the El Niño, except in cases of moderate to strong positive anomalies where the precipitation rates have exceeded 900 mm, The wind and wave regimes present a clear seasonal behavior influenced by the position of the Intertropical Convergence Zone (ITCZ), with greater influence of the trade winds from the north during the months of January to April and southwesterly winds along the rest of the year.Downloads
