• Abstract

  This proposal aims to connect Brazilian researchers with Dr. Andrew Heymsfield, an important international name on hail research. The activities will be divided into two categories, one aimed at graduate students and another aimed at professors and researches. In the first one, the visitor will teach a 2-week course on the processes involved in the development of precipitation (either liq…

• Abstract

  Airborne particles, also called particulate matter, can impact directly and indirectly on earth's climate as well as on human and animal health. Aerosol particles range from a few microns down to very small sizes, such as a few tens of Angstroms. These particles can directly absorb or reflect solar radiation within the atmosphere affecting directly the earth's energy balance, a major focu…

• Abstract

  Amazonia is a living laboratory to study critical processes that regulate tropical atmospheric Chemistry and Physics. The forest is an important global source of aerosols, trace gases and water vapor, and the complex nonlinear processes that regulate these different components are still not fully understood. In this project, we will study Aerosol Life Cycle (ALC), Cloud Life Cycle (CLC), …

• Abstract

  Destructive hailstorms have caused significant damages to agriculture and infrastructure in Brazil, with losses over 2 billion reais in the last decade. Numerous studies suggest that extreme rainfall events in South-Southeastern Brazil, the most hail-prone region in the country, can be produced by mesoscale convective complexes, extratropical cyclones, and heat and moisture transport, esp…

• Abstract

  Deep convective clouds have high impact on modern society given its ability to generate electrification and intense precipitation. However, its predictability is still poor because of the complex nature of the process involving the formation and development of thunderstorm clouds. This project aims to contribute to the nowcasting of such systems by studying the evolution of macro and micr…

• Abstract

  Amazonia is a key environment for the global climate, controlling the water cycle and transport of heat and moisture from the tropics to temperate zones in South America. With agricultural and livestock expansion, this delicate ecosystem has undergone severe changes in recent decades, with strong implications for the hydrological and energy cycle. In this work, we aim to understand how ch…

• Abstract

  This BEPE proposal has the aim of filling the conceptual gap of the associated domestic project. The latter is focused on studying macro- and microphysical aspects of rain as seen by a X-band radar. Given that a significant portion of the rain that reaches the surface is created by ice and mixed processes, there is a need to further study those aspects. The proposed activities of this BEP…

• Abstract

  Known as the fifth largest hydrographic basin in the world and the second largest in the american continent, the La Plata basin has a large hydroelectric potential with several plants placed on its rivers as Itaipú (the largest operating hydroelectric facility in terms of annual energy generation). The La Plata Basin is located on of most densely populated regions in South America, sustai…
