Water Lifting and Outflow Gain of Kinetic Energy in Tropical Cyclones.
While water lifting plays a recognized role in the global atmospheric power budget, estimates for this role in tropical cyclones vary from no effect to a major reduction in storm intensity. To better assess this impact, here we consider the work output of an infinitely narrow thermodynamic cycle wit...

Extreme Precipitation Events in the Northeast Brazil during the winters of 2022 and 2023.
This study aims to evaluate the synoptic conditions responsible for two extreme precipitation events development that occurred in the same region on the east coast of Northeast Brazil (NEB) in two different years, on July 1, 2022 (185 mm/24h), and July 7, 2023 (213 mm/24h). These events are becoming...

Influence of sample preparation methods on FTIR spectra for taxonomic identification of tropical trees in the Atlantic forest.
The Atlantic forest is one of the world's major tropical biomes due to its rich biodiversity. Its vast diversity of plant species poses challenges in floristic surveys. Fourier transform infrared spectroscopy (FTIR) enables rapid and residue-free data collection, providing diverse applications in or...

Sink or carbon source? how the Opuntia cactus agroecosystem interacts in the use of carbon, nutrients and radiation in the Brazilian semi-arid region.
Anthropogenic disturbances directly influence environmental processes and increase the concentration of carbon (C) in the atmosphere. Here, we compare the differences in the seasonality of the balance of carbon, energy, and radiation, as well as seek to identify the interrelationships between these ...
