| Abstract | An automatic environmental monitoring network of 38 surface stations that cover most of Paraná State, in southern Brazil, is maintained by Instituto Tecnológico SIMEPAR since 1997. Despite not characterizing a true mesonet (as the Oklahoma Mesonet, for example), this regional surface network has shown, to a certain extent, the capability of detecting some interesting mesoscale features associated with convective activity. To illustrate that, a couple of such events are described in this article. The first event refers to a convectively-induced mesolow in western Paraná associated with a dissipating mesoscale convective system (MCS) over Paraguay. From the late morning to early afternoon of 17 February 2004, localized one-hour-average pressure drops reaching -5.0 hPa/h were reported by SIMEPAR's stations on the far west Paraná state. In contrast with typical synoptic-scale pressure falls, this substantial pressure drop was accompanied by clear skies. Satellite imagery showed the intrusion of stable air over western Paraná during the pressure fall, just downstream of a decaying MCS across the border with Paraguay. These characteristics are consistent with the conceptual model of convectively-induced pressure features around dissipating MCSs, characterizing a mesolow which is a mesoscale pattern typically dificult to detect with conventional synoptic-scale observing networks. Another example of convective circulation captured by a SIMEPAR's station was a localized pressure rise of 3.9 hPa/h accompanied by a temperature drop of -5.2C/h and wind gusts reaching the severe weather limit of 25,0 m/s reported by Toledo's station (western Paraná) on 15 October 2005. These features were associated with advancing mesohigh, cold pool and gust front induced by a nocturnal convective system, as confirmed by SIMEPAR's weather radar. These patterns highlight the importance of automated observing networks on the regional scale for the detection of mesoscale circulations. | |||
