The sensitivity of the thunderstorm activity in the city of São Paulo to temperature changes: predicting the future activity for different scenarios.
Thunderstorms are part of the complex and interactive processes that form the climate. Its variability can arise from a number of factors, some internal others external to the climate system. In consequence, our ability to predict future climate changes in the thunderstorm activity depends on a bett...

Climate change impacts in the brazilian semi-arid region.
The Brazilian northeast is a region characterized by a semi-arid climate, with precipitation highly variable spatially and in time, with high atmospheric evaporation demand. Model simulation, associating future climate change to anthropogenic use of the soil, suggest an even drier climate in the reg...
