“…For instance, the urban area of Campinas increased from 12.3 km 2 in 1940 to 197.1 km 2 in 1990. In contrast, the city of Rio de Janeiro started to grow in the middle of the 19th century and the increase of urban area is more pronounced in the beginning of the 20th century, being less significant after the middle of the 20th century [ Marenga , ; Lucena et al ., ]. This difference can be seen by the population of cities in the beginning of the 20th century, because the urban area of a given city is linked to the size of its population, as suggested by Oke [].…”

In this report thunderstorm day monthly records obtained in three cities of southeast Brazil (São Paulo, Campinas, and Rio de Janeiro) since the 19th century are analyzed. The analysis is complemented by the spatial distribution of lightning in the last decade. For São Paulo and Campinas, data indicate a significant increase in thunderstorm activity during the period from the end of the 19th century to the present, simultaneously to an increase in the surface temperature well correlated to the population growth of the cities. This result did not match anything expected from natural climate cycles and gives strong observational evidence for the anthropogenic influence on the thunderstorm activity. For Rio de Janeiro, data did not show a significant positive trend from the middle of the 19th century to the present in spite of the increase in the surface temperature, suggesting that variations are most probably a result of a complex combination of local and large‐scale features. In addition, a statistical analysis of the data after 1951 shows that a significant increase (by a factor of 3.7) in the thunderstorm activity in Rio de Janeiro occurs for the simultaneous occurrence of a positive anomaly of the South Atlantic sea surface temperature and La Niña, compared to the simultaneous occurrence of a negative anomaly and El Niño, even though no significant variation was found when each large‐scale phenomena occurs isolated. The same occurs for São Paulo and Campinas, although with a lower amplitude.

“…With one of the world's largest economies and the Amazon as the planet's biggest ecosystem, Brazil indicates a high vulnerability to the impacts of climate change. During the past decades, Brazil was confronted with an uprising trend in minimum and overall surface temperature, especially targeting urbanized areas (Lucena et al, 2013), and was challenged by one of the strongest El Niño Southern Oscillation events that occurred in 2015/2016 (Caminade et al, 2017). In the future, a further rise in warming trends and an increase in the occurrence of weather extremes like floods or droughts are presumed (WHO, 2015).…”

a b s t r a c tThe increases in greenhouse gas concentrations caused by anthropogenic activities such as industrial emissions, transport and burning of forests and other resources, recorded over the past decades, are known to have an impact on the global environment. In particular, this paper reviews the evidence that climate change has an impact on human health as a whole and on the spread of vector-borne diseases in particular. It offers an analysis of previous research on the connections between climate change and health, with a case study from Brazil, and lists some areas which may guide future policy-making.

“…This is a system of semipermanent high pressure, characterized by the presence of horizontal synoptic winds that rotate counterclockwise, vertical subsidence wind that generates divergence near the surface, clear sky, calm weather, and stable conditions, such that the SASA location and intensity change seasonally (Richter et al, 2008;Zeri et al, 2011). The influence of the SASA contributes to inhibit cloudiness and the advancement of high-latitude frontal systems in the region of interest (Lucena et al, 2012). Meteorological mesoscale and microscale systems, such as the sea breezes that act in the MARJ, can be hidden by the SASA system, but they are not totally destroyed as is the case when fronts pass by the area.…”

Influence of high-resolution surface databases on the modeling of local atmospheric circulation systems

Abstract. Large-eddy simulations are performed using the Advanced Regional Prediction System (ARPS) code at horizontal grid resolutions as fine as 300 m to assess the influence of detailed and updated surface databases on the modeling of local atmospheric circulation systems of urban areas with complex terrain. Applications to air pollution and wind energy are sought. These databases are comprised of 3 arc-sec topographic data from the Shuttle Radar Topography Mission, 10 arc-sec vegetation-type data from the European Space Agency (ESA) GlobCover project, and 30 arc-sec leaf area index and fraction of absorbed photosynthetically active radiation data from the ESA GlobCarbon project. Simulations are carried out for the metropolitan area of Rio de Janeiro using six one-way nested-grid domains that allow the choice of distinct parametric models and vertical resolutions associated to each grid. ARPS is initialized using the Global Forecasting System with 0.5 • -resolution data from the National Center of Environmental Prediction, which is also used every 3 h as lateral boundary condition. Topographic shading is turned on and two soil layers are used to compute the soil temperature and moisture budgets in all runs. Results for two simulated runs covering three periods of time are compared to surface and upper-air observational data to explore the dependence of the simulations on initial and boundary conditions, grid resolution, topographic and land-use databases. Our comparisons show overall good agreement between simulated and observational data, mainly for the potential temperature and the wind speed fields, and clearly indicate that the use of high-resolution databases improves significantly our ability to predict the local atmospheric circulation.
