NICOP - Diurnal Variability of Wind Around the Philippines
Abstract
Diurnal cycle variability may be a significant component of the total variability in the climate of the Maritime Continent in general and Philippines in particular. The diurnal may even play an important role in the propagation of intraseasonal tropical oscillations. This study is thus proposed to do a time series analysis of winds around the Philippines. Using data from the Advanced Scatterometer (ASCAT) and a Weather Research and Forecasting (WRF) model, spectral analysis of wind magnitude and direction will be done to determine spatial patterns in the magnitude of the diurnal frequency around the different islands of the Philippines. Strength of the diurnal cycle will then be correlated with other upper ocean, land, and atmospheric variables to determine if variation in the diurnal amplitude is a function of land-sea temperature difference, and type, topography, and size of adjacent watersheds. Other activities will include collection of meteorological and surface ocean data for validation and analysis of effects of diurnal wind variability. This project is tied to the ONR-DRI Propagation of Inta-Seasonal Tropical OscillatioNs (PISTON) and will be preparatory to the proposed observational periods of said DRI, with an expected output of a report/draft of journal article, attendance to YMCplanning workshop and meeting with collaborators in the US to prepare a cruise plan.
