Thermally driven circulations over urban areas, such as sea, lake, and land breezes mountain-valley heat island (UHI) circulations, strongly determine local weather air quality conditions highly populated areas. This study investigates the influence of sea breeze (SB) propagation on development boundary layer (UBL) in Metropolitan Region Sao Paulo (MRSP), Brazil, an area with complex topography. investigation is undertaken observationally by analyzing surface upper observations conducted...
Abstract The main features of low‐level jet (LLJ) in the metropolitan region São Paulo (MRSP), Brazil, are assessed using rawinsondes carried out: (a) every 3‐hr during 10‐consecutive days summer and winter field campaigns MCITY BRAZIL Project 2013, (b) at 0900 2100 local time, from September 2009 to August 2013. These observations indicate that LLJ is a typical feature MRSP, observed 85% 20 field‐campaigns 77.6% 1,446 regular rawinsonde period. fine temporal spatial resolution soundings...
Abstract A rapid verticalization to accommodate the citizens of Metropolitan Region São Paulo is altering balance radiation and atmospheric heat, highlighting need understand impact that green built infrastructure have on canopy urban heat island phenomenon. This meteorological phenomenon occurs mainly due difference in landscape between rural areas. Hypothetical scenarios with different profiles were simulated using WRF model coupled SLUCM, their results compared current scenario numerical...
Main properties of the Low-Level Jet (LLJ) in metropolitan region São Paulo (MRSP) are numerically simulated with WRF (Weather Research Forecasting) model for two 10-day field campaigns MCITY BRAZIL Project, carried out February 19-28 (Summer) and August 6-15 (winter) 2013. The was able to simulate 66.6% observed LLJ events, displaying a high degree agreement main properties. These modeling results confirmed that presence an Upper Tropospheric Cyclonic Vortex northeast MRSP during summer...
This study uses in situ measurements, satellite data, and modeling techniques to investigate methane (CH 4 ) emissions from the Caieiras landfill São Paulo, Brazil. Methane is second most significant greenhouse gas due its high heating potential. Previous studies have shown that landfills can be considered super-emitters of methane. Quantifying essential comprehending patterns this emitter, promoting an improvement data inventories. Multiple platforms were used obtain better characterize...
Ozone events in South America might be triggered by increasing air temperatures and dry conditions, leading to vulnerable population exposure. The current quality standards attention levels São Paulo state, Brazil, are 40% higher 25% higher, respectively, than the limits recommended World Health Organization (WHO). We simulated an extreme ozone event megacity using Weather Research Forecast/Chemistry model during characterized positive anomalies of temperature solar radiation. Results were...
Abstract The main features of the urban boundary layer in metropolitan region São Paulo are estimated based on rawinsondes carried out (a) every 3 hr two 10‐day field campaigns MCITY BRAZIL Project during summer and winter 2013 (b) regularly once per day continuously for 4 years from 2009 to 2013. On average, height showed a daytime maximum 1476 ± 149 m 1122 168 campaigns. differences related seasonal variations buoyancy flux at surface, which was 30% larger (4.7 0.6 MJ −2 −1 ), static...
A coupled atmospheric-oceanic model was used to investigate whether there is a positive feedback between the coastal upwelling and sea breeze at Cabo Frio - RJ (Brazil). Two experiments were performed ascertain influence of on upwelling: first one forced with synoptic NE winds 8 m s-1 sign circulation set by atmospheric model; second experiment only oceanic constant winds. Then, study breeze, two more performed: using representative SST initial field other homogeneous 26°C. Finally,...
The Environmental Agency of Sao Paulo has a large dataset carbon monoxide measurements: 20 years records in 18 automatic stations inside the metropolitan area. However, thorough investigation on time evolution CO concentration tendency and cycles also considering spatial variability is lacking. consists trend line analysis, periodogram correlation between meteorological variables, distribution concentration. Local federal policies helped decreasing concentrations highest rate was 0.7% per...
We herein report new records of Parides burchellanus (Westwood, 1872) in southwestern Minas Gerais state, Brazil, areas the upper São Francisco and Araguari river systems, including buffer zone Parque Nacional da Serra Canastra. Until recently, only known colonies P. were located municipalities Brumadinho, Planaltina, Distrito Federal, some 640 km apart from each other. The implications these to conservation status this species are discussed.
Abstract Air pollution is associated to poor urban mobility conditions, as in the megacity of São Paulo. Three scenarios policies driving restrictions were simulated using WRF/Chem model, assess impacts on ozone and consequences for environmental justice: toll, sustainable transition, vehicle free zone. Results show that toll leads a decrease 20 µg.m-3 maximum 8-hour averages prevention six hours exceedances air quality standard. Sustainable transition was most promising scenario, with 50...
Abstract The climate modeling techniques of event attribution enable systematic assessments the extent that anthropogenic change may be altering probability or magnitude extreme events. In consecutive years 2018, 2019, and 2020, rainfalls caused repeated flooding impacts in lower Parnaíba River Northeastern Brazil. We studied effect alterations precipitation resulting from human influences on had likelihood using two ensembles HadGEM3‐GA6 atmospheric model: one driven by both natural...
