A June climatological distribution of rainfall for Luzon has been constructed. The method of construction consists of combining two types of rainfall values: theoretical values from simulations with an atmospheric model and observed values at rain gauge stations. The method has been applied...
In response to the serious implications of changes in the local climate, this study describes the temporal and spatial rainfall variability in the Philippines. Precipitation and wet-day frequency are obtained from the 0.5-degree resolution gridded dataset of monthly surface climate of global land...
The dependence of pollution patterns in the coastal waters of Lingayen Gulf on the prevailing winds is studied with the aid of a theoretical model. The model equations consist of the well-known vertically integrated hydro-dynamical equations and a mass transport-dispersion equation. The model...
Flooding due to sea level rise is a primary concern brought about by climate change. This study focuses on Northern Navotas, Metro Manila, a densely populated urban area affected by frequent diurnal changes in sea level. The study verifies terrain data vis-a-vis its...
A method for developing a high resolution, accurate gridded, rainfall data for the Philippines is described. The method is based on combining three types of climatological rainfall information. The first type consists of gridded data which are obtained by using rainfall simulations 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 analysis shows that the...
This study investigates the changes in the surface temperature and wind field due to the possible southward growth of the Metro Manila urban area. Twenty days in April 2002 are simulated using the Fifth-Generation PSU/NCAR Mesoscale Model (MM5). In order to isolate the...

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...
Climate studies call for more localized climate scenarios. The scarcity of high-resolution scenarios is a problem, however. To address this problem, we aimed to construct an artificial neural network (ANN) that performs climate downscaling for an area in Luzon, Philippines. In this paper,...
The paper is a summary of the more important factors affecting sea level rise. Geodynamic factors are elaborated and explained, based on numerous studies affecting such phenomena. The contributions of time varying, temperature dependent factors are explicitly discussed and elaborated, and some related...
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...
This paper is an initial research on a high-resolution model of the mesoscale circulations over Metro Manila using the Fifth-Generation PSU/NCAR Mesoscale Model (MM5). Two days in April 2002 characterized by a calm prevailing wind were simulated. The model indicated the occurrence of...
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...
General Circulation Model based on the Special Reports on Emissions Scenarios are downscaled in order to determine future possible climate conditions in the Philippines.
The diurnal variation of air pollution over Metro Manila is studied by means of model simulations. The model equations are based on the fluid dynamical equations. The equations are integrated for the case when the prevailing wind is calm and with a prevailing...
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...
