Análisis espacio-temporal meteorológico en una cuenca andina tropical del sur de Ecuador

Abstract

This research project focused on the search for patterns and analysis of interrelationships between meteorological variables (precipitation, air temperature, relative humidity, atmospheric pressure, global solar radiation, wind speed and wind direction) on a spatial and temporal scale in an Andean basin in southern Ecuador. Moreover, the performance of meteorological satellite products from the European Centre for Medium-Range Weather and Forecasting (ECMWF) on hourly, daily, and monthly scale for each variable was determined. Hourly data was available recorded in thirty weather stations from two networks: Empresa Municipal de Telecomunicaciones, Agua Potable y Saneamiento (ETAPA-EP), and Universidad Politécnica Salesiana (UPS). First, data quality assessment and Exploratory Data Analysis (EDA) were developed. Filling missing data was conducted using Multiple Imputation by Chained Equations (MICE). Unsupervised classification was applied through clustering for spatial analysis of meteorological data. Using the meteorological datasets, altitudinal variations of each meteorological variable were determined. Regarding temporal analysis, time series profiles for different scales were constructed and analyzed, also, extreme events of temperature and precipitation were identified. Results demonstrated the behavior and associations of meteorological variables in space and time. Finally, hopeful performances of ERA5 and ERA5-Land satellite meteorological products were found compared to weather station observations.
