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 - Galeao
International Airports (SBGL), located in the city of Rio de Janeiro,
evaluating its thicknesses and its relations with the astronomical
tides. In addition, a case study was chosen to subsidize early
investigations, and relationships with phenomena of synoptic scale.
