dc.description.abstractTropical Easterly waves (TEWs) are important contributors to precipitation and extreme precipitation events (EPEs) in tropical regions during their most active seasons; June to August (JJA) and September to November (SON). This thesis studies the influence of Tropical Easterly Waves in two convection processes, general precipitation and EPEs over Northern South America and Southern Central America during their most TEWs active seasons, JJA and SON. Using the recent TEWs chronology by Hollis (2024), the high spatial resolution precipitation dataset by GPM, and atmospheric variables from ERA5, we quantify percentage changes in these convective processes and analyze their associated synoptic environments. The results show that convective and dry TEWs have an stronger influence over general precipitation from 5°N to 20°. In particular, convective TEWs contribute to increased precipitation, while dry TEWs have the opposite effect, with dry TEWs extending their influence over the Andean region up to the equator. Regarding EPEs composites, each classification of TEWs presents contrasting seasonal patterns, but the sign of percentage changes aligns with that of general precipitation. Convective TEWs show the highest precipitation perturbations over the Caribbean during SON, while dry TEWs display them during JJA. Our findings highlight the importance of classifying TEWs into convective and dry, for both convective processes, general precipitation, and EPEs. We also describe the synoptic environments associated with these results, providing insights into the mechanisms that help to explain the observed changes. (Tomado de la fuente)eng
dc.description.abstractLas Ondas Tropicales del Este (TEWs, por sus siglas en inglés) son importantes para la formacion de la precipitación y los eventos extremos de precipitación (EPEs) en las regiones tropicales durante sus temporadas de mayor actividad: de junio a agosto (JJA) y de septiembre a noviembre (SON). Esta tesis estudia la influencia de TEWs en dos procesos convectivos, la precipitación general y los EPEs, en el Norte de Sur América y Centro América durante sus temporadas de mayor actividad. Utilizando la cronología de TEWs publicada recientemente por Hollis (2024), la base de datos de precipitación de alta resolución espacial de GPM y variables atmosféricas de ERA5, cuantificamos los cambios porcentuales en estos procesos convectivos y analizamos sus entornos sinópticos. Nuestros hallazgos resaltan la importancia de clasificar las TEWs en Convectivas y Secas para ambos procesos convectivos, la precipitación general y los EPEs. Las TEWs Convectivas y Secas tienen una influencia más fuerte sobre la precipitación entre los 5°N y los 20°N, con las TEWs Secas extendiendo su impacto sobre la región andina hasta el ecuador. En cuanto a los compuestos de EPEs, cada clasificación de TEWs presenta patrones estacionales contrastantes, aunque el signo de los cambios porcentuales se alinea con el de la precipitación general, las TEWs Convectivas muestran los valores más altos sobre el Caribe durante SON, mientras que las TEWs Secas los muestran durante JJA. Además, describimos los entornos sinópticos asociados a estos resultados, proporcionando información sobre los mecanismos que explican los cambios observados.spa
