Research Lines

 

The Meteorology Graduate Program is associated with the Atmospheric Sciences Department. Students develop projects which contribute significantly to research areas studied by professors. These areas can be divided into the following:

1. Micrometeorology

The focus of this topic is the studies of micro and mesoscale meteorological phenomena with applications on analysis of the impact of anthropogenic sources. Observational research of turbulent exchange processes in the atmosphere and ocean which affect the atmospheric boundary layer. At the Micrometeorology Laboratory, researches are performed involving the study of planetary boundary layer dynamics, numerical modeling of atmospheric turbulence and applications to atmospheric pollutant dispersion.

A major part of the studies involves collecting data through a micrometeorological platform which continuously measures direct, diffuse and global solar radiation (since 1994) and long wave radiation (since 1997). Researches in this area are also conducted in the Laboratory of Air-Sea Interaction. The boundary layer in oceanic regions is surveyed by measuring turbulent fluxes and vertical profiles of oceanic and meteorological parameters obtained with an instrumented tower located at the western region of the Tropical Atlantic Ocean.

Researchers: Amauri Pereira de Oliveira and Jacyra Ramos Soares


2. Weather and climate studies and applications

 
This is one of the broadest research areas in the Atmospheric Sciences Department. It involves observational studies and numerical simulations of atmospheric phenomena, from small to global scales. Understanding the interrelationship between different scales is also an objective of researches carried out in this area. Studies on climate seek to improve and adapt regional climate models to the state of São Paulo, used for both forecasting and research.

Weather study applications encompass the use of remote sensing technology (satellite, radar, SODAR) and development of mesoscale and oceanic numerical models which may be used in several other research lines studied in the department.

3. Atmosphere-biosphere-ocean interaction


Multidisciplinary research projects are conducted in this line of research. Main Brazilian ecosystems and agroecosystems are investigated by being characterized on a functional biophysical perspective. This field of study addresses processes of water supply and usage, primary productivity, energy and carbon fluxes within the atmosphere. It also encompasses the subjects of forecasting, sustainability and climate change impacts.

Most of the surveys use data collected in several instrumented towers over ecosystem areas of the Cerrado (Santa Rita do Passa Quatro, SP ), Ecotone (Ilha do Bananal, TO), sugarcane production areas (Luiz Antônio, SP) and eucalyptus production areas (Santa Rita do Passa Quatro, SP). The gathered information is used in the development and application of hydrological and soil-surface-atmosphere interaction models.

4. Atmospheric pollution

 
This research line integrates projects that investigate formation, transport and removal processes of atmospheric constituents in urban and rural areas near the tropics. Studies developed in this area focus on the following themes: chemical and physical characterization of atmospheric aerosols; models for gas and particulate matter removal; wet deposition (rain water) chemical characterization; evaluation of dry and wet deposition processes; modeling of dispersion and formation of atmospheric pollutants - photochemical smog; quantification and classification of bioaerosols; biometeorology.

5. Physics of atmospheric processes and applications

 
This research line involves theoretical foundations of cloud thermodynamic and microphysical processes, storm electrification and atmospheric radiative transfer processes. Algorithms are used and upgraded based on theoretical knowledge allowing inference on rain and hydrometeor properties, aerosol optical properties and atmospheric water vapor content. Observations made through satellites with radars and radiometers in different spectral regions are analyzed with the intent to better describe 1) effects of aerosols in meteorology and climate, 2) radiation balance components and 3) the hydrological cycle.

6. Hydrometeorology

 
In this research line, studies are performed aiming the continuous development of hydrometeorological forecasting systems with applications in water resources, hydrology, generation, transmission and distribution of electric power, urban and rural environments, civil defense, etc. These systems require research and development in atmospheric and superficial numerical models, coupled with the hydrological cycle atmospheric and superficial stages in order to produce better forecasting.

The main fundamental and applied researches are developed based on studies of surface and altitude measurement systems, radar assisted remote sensing, profiler and environmental satellites, diagnostics and prognostics studies of atmospheric and surface processes based on numerical modeling and parameterizations when space-time scales are not determined or directly measured. Development of numerical and concept modeling is also included.
