Objetivo general del presente trabajo de suficiencia profesional es el desarrollar e implementar el modelo de dispersión de cenizas volcánicas FALL3D y el modelo WRF para escenarios climáticos en el SENAMHI.

The present work has as objective the elaboration of a new gridded data base to 16 km, for the analysis of the changes of the future climate on Peru, mainly in the variables of precipitation, maximum and minimum temperature. The methodology used is the dynamic regionalization technique, using the regional climate model Weather Research and Forecasting (WRF), using the initial conditions of the HadGEM2-ES global model, for the period of 1981-2065, with the RCP 8.5 emission scenario. The analysis of the results for the observed period indicates a better representation of the precipitation in the central and southern part of the Peruvian Andes and overestimation mainly in the summer period (December, January and February). With regard to temperatures, there is a better representation of the minimum temperature compared to the maximum. While the results of the changes to 2030 indicate non-un...

In June 2018, the Peruvian provinces of Arequipa and Puno in the southern Andean region were affected by heavy snowfall, which caused severe damage to people and livelihoods in several communities. Using the Forecast-based Financing approach, the Peruvian Red Cross implemented its pre-defined early action protocol before this event, after receiving an extreme snowfall warning (Level 4) from the Peruvian meteorological service. Here, we provide a case study of the approach and event itself, documenting the decision-making thresholds as well as the actions taken. This warning activated the thresholds established in the protocol, and Peruvian Red Cross prioritized 10 communities for pre-disaster support based on the forecasted severity of the event in combination with vulnerability and exposure information. The activation took place 2 days before the extreme snowfall in the communities, and...

This study focused on estimating precipitation for the Santa basin located north of the capital of Peru, assessing spatial patterns and temporal variation. Precipitation products were used at a daily temporal resolution obtained from remote sensing datasets, including CHIRPS, PERSIANN-CCS, GPM and PISCO, altitude and vegetation products as NDVI-BOKU and GDEM. Also ground-based precipitation data from weather stations were collected from 35 meteorological stations (2012 -2019)

Peruvian glaciers are important contributors to dry season runoff for agriculture and hydropower, but they are at risk of disappearing due to climate warming. Their energy balance and ablation characteristics have previously been studied only for individual glaciers, with no comparisons between regions. We applied the physically-based, energy balance melt component of the model Tethys-Chloris at five on-glacier meteorological stations: three in the Cordillera Blanca near Huaraz (with glaciers above ~4300 m a.s.l.), and two in the Cordillera Vilcanota east of Cusco (with glaciers above ~ 4800 m). The climate of these regions is strongly seasonal, with an austral summer wet season and winter dry season. Our results revealed that at most sites the energy available for melt is greatest in the wet season. This is a consequence of the dry season energy losses from the latent heat flux and net ...
