Influencia de la variabilidad climática sobre el ciclo atmosférico diurno en los ecosistemas del Ecuador: Casos de estudio en Galápagos y en el volcán Antisana

Abstract

In the present investigation, the diurnal meteorological cycle of the Antisana and Galápagos volcano ecosystems is studied. The variations in the behavior of the climatological variables during the delimited seasons are analyzed and it is examined how the diurnal cycle has been affected by external climatological phenomena. Constructing a Data base made up of hourly, daily, monthly and annual cut-off of the Meteorological variables, the Annual and Daytime Cycles are determined, anomalies are detected in Annual Averages and with the use of Correlations Between the variables are delimited. anomalies The months where the SST (Region 3) shows the presence of the ENSO phenomenon are delimited and differences are detected with the average months; Finally, the process for the diurnal cycles is repeated in the events of the child of both study areas. The radiation and precipitation contain slight and severe excesses between 09h00 and 16h00, the temperature and speed of the wind during the 24 hours reflect slight excesses and severe; while the relative humidity undergoes the opposite effect. In the Nina events the experimental variables are opposite to those of El Niño, an exception of radiation where a trend is not described. Variables such as relative humidity and wind speed are sensitive to ENSO on a diurnal scale whereas on an interannual scale they are not.
