Article 0 Reads 1 Citation Local Convection and Turbulence in the Amazonia Using Large Eddy Simulation Model Theomar Neves, Gilberto Fisch, Siegfried Raasch Published: 12 October 2018
Atmosphere, doi: 10.3390/atmos9100399
DOI See at publisher website ABS Show/hide abstract
Using a high resolution model of Large Eddies Simulation (LES), named PALM from PArallel LES Model, a set of simulations were performed to understand how turbulence and convection behave in a pasture and forest sites in Amazonia during the dry and rainy seasons. Related to seasonality, dry period presented higher differences of values (40 W m−2) and patterns over the sites, while in the wet period have more similar characteristics (difference of −10 W m−2). The pasture site had more convection than the forest, with effective mixing and a deeper boundary layer (2600 m). The vertical decrease of sensible heat flux with altitude fed convection and also influenced the convective boundary layer (CBL) height. Regarding the components of turbulent kinetic energy equation, the thermal production was the most important component and the dissipation rate responded with higher growth, especially in cases of greatest mechanical production at the forest surface reaching values up to −20.0.

This paper presents general aspects of the water budget (including the latest available figures from its components), followed by some characteristics of the rainfall along the Paraiba do Sul watershed. The regional water budget theme is then discussed, taking into account the actual and future rainfall in the region. Finally, reflections and discussions regarding the water security theme (represented by the water transposition from the Paraiba do Sul watershed to the Cantareira´s system) are discussed, as the latter represents the water demand of São Paulo City. The future scenarios of the water availability are estimated using a climatic simulation model.

The moisture transport from the Amazon to the Southeast (SE) of Brazil is an important atmospheric mechanism that contributes to the high precipitation rates during the austral summer (DJF) in this region, or more specifically, in the Sao Paulo state (27 and 20oS and longitude between 315 and 305oW). This transport originates from the entrance of moisture from the North Atlantic Ocean, moving to inside of the Amazon (10oS and 3oN, and longitude between 290o and 310oW), where it is supplied by rivers and aerial lakes, resulting of rain forest evapotranspiration. After this supply, the moisture flow is diverted to larger latitudes (South and Southeast) due to the Andes mountain range. Another important system that also assists precipitation in the SE region during the summer period is the frontal systems that are supplied by the transport of this moisture and, when they remain stationary, form a large band of cloudiness with NW / SE orientation, called the South Atlantic Convergence Zone (SACZ), which supplies, along with the frontal systems (on average 5 passes during the summer (DJF)) the SE region. This integrated vertical moisture transport (from the surface up to 500hPa) was studied for the years that occurred El Niño Southern Oscillation (ENSO) events and in neutral years. The results show an intensification of this flow in years of ENSO. In neutral years, thereabout 45.1 kg / kg enter the Amazon territory and thereabout 27.5 kg / kg of this moisture exits, and in the region of São Paulo it receives an average amount of 8.9 kg / kg and loses 7kg / kg. When the ENSO phenomenon occurs, the flow pattern increases significantly in the two regions: the input (54.8 kg / kg) and the outflow (47.4 kg / kg) in Amazon are larger, with São Paulo receiving 42, 2 kg / kg and loses 11.8 kg / kg of all moisture received. In years of ENSO, there is an intensification of the jet stream in the central part of Brazil, blocking the passage of frontal systems. The reduction of precipitation in this period in the SE region by the SACZ is compensated by the greater humidity transport from the Amazon, and therefore, not changing in the precipitation pattern.

This paper introduces a new approach to represent the rocket exhaust effluents into an atmospheric dispersion model considering the trajectory and variable burning rates of a Satellite Vehicle Launcher, taking into account the buoyancy of the exhausted gases. It presents a simulation for a Satellite Vehicle Launcher flight at 12:00Z in a typical day of the dry season (Sept 17, 2008) at the Centro de Lançamento de Alcântara using the Weather Research and Forecasting Model coupled with a modified chemistry module to take into account the gases HCl,CO,CO2, and particulate matter emitted from the rocket engine. The results show that the HCl levels are dangerous in the first hour after the launching into the Launch Preparation Area and at the Technical Meteorological Center region; the CO levels are critical for the first 10 min after the launching, representing a high risk for human activities at the proximities of the launching pad.
