                         decades, directly impacting the number, intensity and duration of 
                         extreme events such as heat waves. Climate model projections 
                         accounting for anthropogenic factors indicate that deadly 
                         mega-heat waves are likely to become more frequent in the future. 
                         Although the atmospheric features and social-economic related 
                         impacts of heat waves have already been documented in various 
                         regions around the world, for other highly populated regions, such 
                         as the Metro politan Region of Rio de Janeiro (MRRJ), a similar 
                         objective assessment is still needed. Heat waves directly impact 
                         the public health sector and particularly the less wealthy and 
                         elderly population groups. During February 2010, an elevated 
                         mortality peak occurred during a 8-day period (from 2 to 9 Feb 
                         2010) characterized as a heat wave episode in MRRJ. A total excess 
                         of 737 deaths was recorded with the elderly group registering the 
                         highest mortality incidence. During this heat wave period, a 
                         quasi-stationary anticyclonic anomaly forced in altitude by a 
                         Rossby wave train was established over the south Brazilian coast. 
                         At the surface, the meteorological scenario from January 2010 to 
                         the heat wave period was marked by clear sky conditions, large 
                         precipitation deficits, and enhanced diabatic heating. During the 
                         heat wave period, warm and dry air masses were advected from 
                         interior regions towards the MRRJ, exacerbating temperature 
                         conditions by pronounced subsidence and adiabatic heating 
                         mechanisms. All these conditions contributed to pronounced 
                         positive temperature anomalies, reinforced by land-atmosphere 
                         feedbacks.",
