Abstract The impacts of climate change are beginning to be felt around the world. Case studies that identify the immediate causes of disasters as well as their root drivers provide the empirical basis for strategies to increase resilience to climate impacts. Here we...
The problem of the present study is to determine which of the two planes of a Focal Mechanism Solution (FMS) is the fault plane. In order to resolve this problem of ambiguity in focal mechanisms, we use the method of perturbation of the...
This study evaluates the skill of the PSU/NCAR mesoscale model (MM5) in predicting the storm tracks and associated precipitation during tropical cyclone events within the Philippine Area of Responsibility (PAR). Simulated storm tracks and accumulated rainfall forecasts of six tropical cyclones that occurred...
Different methods of clustering are explored to determine the different climate types in the Philippines. This study aims to find a way to reduce data that is varying in both space and time, as in the case of rainfall data, in order to...
The performance of the MM5 and the RegCM3 models in simulating total monthly rainfall has been evaluated. Total rainfall for the two months of June 2000 and June 2001 are simulated. These two months have been selected because they are characterized by two...
A method for computing climatological rainfall is used to determine the rainfall distribution for Luzon during the month of June. The method consists of simulating the distribution with a fluid dynamical model of the atmosphere and merging the results of the simulation with...
Observations of NO2 at the Manila Observatory in the Ateneo de Manila Campus (Quezon City, Philippines) are analyzed. These have been made with a Differential Optical Absorption Spectroscope (DOAS) during the two months of June and August 2002. The concentrations have been analyzed...
A method for developing climatological information of monthly rainfall for the Philippines is described. The information consists of monthly rainfall at a uniform array of grid points. This array can be used to construct climatological rainfall maps and other types of graphical representations...
The diurnal variation of air pollution over Metro Manila is studied by using a theoretical model. The model equations consist of a set of fluid dynamical equations and an equation of mass transport for predicting air pollution. The dynamical equations are based on...
Visualization of the extent of climate change in the Philippines is important in vulnerability and adaptation studies. Data will have to be downscaled from the result of General Circulation Models (GCMs) modelled by the developed countries. Three different models were studied and compared...
The possibility of predicting rainfall anomalies in the Philippines due to El Niño and La Niña is investigated. The data used in the investigation consist of rain gauge observations, satellite-derived rainfall and sea surface temperatures in the Central Pacific Ocean. The investigation is...
The changes in rainfall patterns, which evolve during the growth in size of a tropical urban area, are studied by means of model simulations. The urban area is located along a coastline. The simulated rainfall is produced by mesoscale disturbances during the rainy...
A two-dimensional, theoretical model based on the fluid dynamical equations is developed to determine the effects of urbanization on rainfall. The model is applied to a case where the urban area is located between the sea and the rural area. The model incorporates...
The effect of the urbanization on temperature and on rainfall is studied by analyzing observational data. The primary data used are observations from Port Area and Science Garden.These correspond to locations in the urbanized area. These observations are upplemented by observations at rural...
The characteristics of rainfall and wind during the occurrence of three El Nino episodes and one La Nina episode are studied by using observational data. The episodes correspond to the El Nino of the years 1983, 1987, and 1992, and the La Nina...
A diagnostic study of the rainfall and the wind climatology of the Philippine–South China Sea region has been conducted using data obtained from the ECMWF reanalysis. The study shows unusually complex rainfall patterns even over the sea where no complications can occur due...
