Spatial characterization of storm's frequency and intensity from theGOES-12 satellite and the meteorological station from HuancayoObservatory

Abstract

Objectives: To characterize the rain storms' frequency and intensity through obtained images from the Geostationary Operational Environmental Satellite (GOES-12) and recorded data at the meteorological station from Huancayo Observatory, during hydrological cycles comprising between july 2012 to june 2014. Methods : It was used the hydro-estimator method which georeference the point and intensity by the exponential empirical relationship between radar estimated precipitation and the cloud tops brightness temperature through the infrared canal which produces precipitation rates in real time and the precipitation intensity method which assesses the intensity rate in millimeters per hour; however, because of the information is recorded in the pluviometer presents biases by boundary effects, we took as a resource the storms analysis in 120 minutes with maximum rain in 12 hours. Results: Rainfall was classified as light (11 events), moderate (8 events), strong (3 events) and extreme (5 events) according to the physical data analysis of the station and rainfall intensities maps were constructed coupled in time-space about two extreme events, also the connection points were presented between precipitation, temperature and atmospheric pressure as well as the satellite images during the extreme storms development. Conclusions: Points and rainfall impact area were identified, also its correlation with precipitation data from the meteorological station from Huancayo Observatory.
