Preliminary Study on Fogs in the Guanabara Bay (Rio de Janeiro-Brazil) Associated with Astronomical Tide by Ana Cristina Pinto de Almeida Palmeira in MAOPS- Lupine Publishers
Studies on fogs report a great diversity of physical processes
involved besides a strong dependence of the place of formation.
The different possibilities of the advective, radiative and mixed
patterns, associated or not to precipitation, make difficult the exact
characterization of its life cycle and, consequently, its
predictability. However, the advancement of satellite image
visualization
techniques as well as the increase in the database available free of
charge at the national (CPTEC / INPE) and international (NOAA)
levels, have improved the detection of this phenomenon after being
formed. This work begins a quantification of the occurrence
of fogs in the vicinity of Guanabara Bay through data obtained at the
Santos Dummond (SBRJ) and Antonio Carlos Jobim - Galeão
International Airports (SBGL), located in the city of Rio de Janeiro,
evaluating its thicknesses and its relations with the astronomicaltides. In addition, a case study was chosen to subsidize early
investigations, and relationships with phenomena of synoptic scale.
