MS Atmospheric Science Thesis Defense of JC Albert Peralta: Intraseasonal Dynamics of the Region of Influence of the Asian Summer Monsoon over the Philippines

Intraseasonal Dynamics of the Region of Influence of the Asian Summer Monsoon over the Philippines

The Department of Physics of the School of Science and Engineering of Ateneo de Manila University cordially invites you to an MS Atmospheric Science Thesis Defense by JC Albert Peralta on April 16, 2019, 10:00 a.m. to 12:00 p.m., at Heyden Hall, Manila Observatory. His thesis is entitled, “Intraseasonal dynamics of the region of influence of the Asian Summer Monsoon over the Philippines,” under the supervision of Dr. Gemma Teresa T. Narisma. His thesis panelists are Ms. Genevieve Lorenzo, Dr. Julie Dado, and and Dr. James Simpas.

Abstract. The Asian Summer Monsoon (ASM) manifests in the Philippines during June to September as a southwesterly wind flow and rainfall predominantly affecting the western side of the country. This study focused on the intraseasonal dynamics of ASM by assessing the area where its climatologically-persistent high rainfall is observed, i.e., its Region of Influence (ROI), over the Philippines. Validation procedures with respect to 49 observation stations reveal that the TRMM 3B42v7 rainfall dataset is best to use among 4 datasets. The ROI is defined as the contour where 3.0mm/p is measured for at least 75% of all pentads. The resulting area is robust in both time coverage, interannual variability and high correlation with surface winds. Orographically-enhanced ascent of moist southwesterly flow over windward areas is seen as general mechanism that produce favorable rainfall conditions over the ROI. The spatial pattern of the ROI inner band revealed 3 distinct curves labeled as the Luzon, Visayas and Mindanao subregions of the ROI, each with their own unique properties. The Habagat Rainfall Index (HRI) was utilized to detect mosoon rainfall exteremes per subregion. Seasonal wet (dry) monsoons seasons develop over the Luzon and Visayas subregions if faster (slower) low-level southwesterly winds due to favorable (suppressing) shear conditions enhances (diminishes) the observed convective cell over the ROI. On the other hand, extremes on Mindanao subregion form when the seasonal low-level westerly winds are slower. Its seasonal wet monsoon seasons also have a similar convection cell enhancement due to westerly flows but coupled with external moisture by less-frequent intraseasonal easterly flow, while suppression of the convection cell mechanism due to less organized upper level features give rise to its dry monsoon seasons.

MS Atmospheric Science thesis defense of Ruby Navarro: Comparison of MO foF2 observations with IRI-2016 model for Solar Cycle 21


The Department of Physics cordially invites you to an Atmospheric Science Thesis Defense:

Ionosonde foF2 observations at Manila Observatory, Philippines for Solar Cycle 21: Comparison with IRI-2016 Model

  • MS Atmospheric Science Candidate: Ruby Jane Navarro
  • Date and Time: 08 April 2019, 3:30-5:30 p.m.
  • Venue: Heyden Hall, Manila Observatory
  • Thesis Adviser: Dr. Quirino Sugon Jr
  • Thesis Panelists: Mr. Clint Dominic Bennett, Dr. Maria Obiminda Cambaliza, and Dr. James Bernard Simpas

Abstract.We studied the historical data for the critical frequency foF2 of the F2 ionospheric layer from an ionosonde at Manila Observatory (MO) in the Philippines (14.7N, 121.1E) for the years 1976 – 1986, a period covering the entire solar cycle 21. A solar cycle is measured by the Wolf’s number, which depends on the number of sunspots. More sunspots correspond to high solar activity, resulting to more molecules ionized in the upper atmosphere, which range from 60 to 1,000 km. The ionosphere has different layers—D, E, F1, and F2–but the layer most responsive to solar activity is the F2 layer. To monitor the F2 layer, an ionosonde sends radio waves from 2 to 30 MHz upwards to the ionosphere. The speed of these radio waves depend on the density of electrons and the wave frequency. The critical frequency foF2 is the maximum frequency that can be reflected by the ionosphere, neglecting the effect of geomagnetic field, i.e., when a radio wave frequency exceeds this value, it may no longer return to the Earth.

In our work, we compared the observed ionospheric values of MO with those of the International Reference Ionosphere 2016 model (IRI-2016) to determine if the model can accurately predict the observed values or whether the model needs to be updated to accommodate the MO data, which consists of monthly median hourly values of foF2. The IRI- 2016 model was run using the geographic location and temporal resolution of MO data, with the following optional input parameters: geomagnetic storm model turned off and the URSI coefficient set for Ne F-peak. The method of statistical moments was implemented in order to obtain characteristics of observed and model comparison values, such as average, root mean square error, skewness and kurtosis. Analysis showed that the foF2 values derived from the MO- IRI 2016 hourly linear calibration curve (MOIRI) fit well with the observed data for the given geographical time and location, as compared to the values obtained by the basic IRI-2016 model run.

by Christian Lorenz S. Mahinay

The Vacuum Society of the Philippines (VSP) in collaboration with the Department of Physics, School of Science and Engineering, Ateneo de Manila University, will be hosting the short topical conference which is free of attendance to all interested persons. The topical conference will center on discussions regarding a multidisciplinary approach in utilizing scientific resources in vacuum sciences and allied fields to raise the economic potential of high-tech industries and developing national research laboratories within the Philippines. Students and guests from Doshisha University, Japan, under the Global Resource Management program, will discuss on the possibility of strengthening the Philippines technological competitiveness through forming an inter-university research network with Japanese universities. Representatives from the Department of Science and Technology (DOST) and Sunpower Philippines Manufacturing Ltd. will also give a talk regarding this topic from the view point of government and private industrial sectors.

Members and associates of VSP, and students can submit abstracts for the conference in both academic fields: business and technology. Selected papers will be invited to give a short oral presentation regarding their work on a special session on the second day of the conference. The scientific committee welcomes wide variety in academic fields.

There will be a guided tour through selected laboratories within Ateneo and UP and a historical tour to the National Museum in Intramuros, Manila on the second day.
