The resolution sensitivity of the South Asian monsoon and Indo-Pacific in a global 0.35◦ AGCM

The South Asian monsoon is one of the most significant manifestations of the seasonal cycle. It directly impacts nearly one third of the world’s population and also has substantial global influence. Using 27-year integrations of a high-resolution atmospheric general circulation model (Met Office Unified Model), we study changes in South Asian monsoon precipitation and circulation when horizontal resolution is increased from approximately 200 to 40 km at the equator (N96 to N512, 1.9 to 0.35◦). The high resolution, integration length and ensemble size of the dataset make this the most extensive dataset used to evaluate the resolution sensitivity of the South Asian monsoon to date. We find a consistent pattern of JJAS precipitation and circulation changes as resolution increases, which include a slight increase in precipitation over peninsular India, changes in Indian and Indochinese orographic rain bands, increasing wind speeds in the Somali Jet, increasing precipitation over the Maritime Continent islands and decreasing precipitation over the northern Maritime Continent seas. To diagnose which resolution related processes cause these changes we compare them to published sensitivity experiments that change regional orography and coastlines. Our analysis indicates that improved resolution of the East African Highlands results in the improved representation of the Somali Jet and further suggests that improved resolution of orography over Indochina and the Maritime Continent results in more precipitation over the Maritime Continent islands at the expense of reduced precipitation further north. We also evaluate the resolution sensitivity of monsoon depressions and lows, which contribute more precipitation over northeast India at higher resolution. We conclude that while increasing resolution at these scales does not solve the many monsoon biases that exist in GCMs, it has a number of small, beneficial impacts.

Research review : searching for a new framework for Thailand's foreign policy in the post-cold war era

Thai foreign policy in the 1990s has been said to be contingent on the government in power, which changes between (or within) these groups and vacillates between pro-democratic reformists/principle-pursuers and the conservatives/profit-seekers. In these studies, Thailand’s Indochinese policy has often been referred to as a typical consequence of politics between the pragmatists and the reformists. However, whether or not domestic oppositional politics is the key determinant of foreign policy in the post-Cold War era still requires further examination, precisely because the model is now facing serious challenges between theory and reality. In this paper, I review the existing arguments concerning Thailand’s foreign policy in the post-Cold War Era and point out their limitations and questions for future study.

Contribution a l'étude des invertébrés de la faune marine benthique de l'Indochine

This paper presents an assessment of a long-term study on the fauna and the maritime domain of the Indochinese Union, western part of the South China Sea.

Inventaire de la faune ichtyologique de l'Indochine: deuxième liste

In 1926, The Oceanographic Institute published a first list of Indochinese fish, prepared by Mr. P. Charanaud. This first inventory included 275 species. For 6 years, researches conducted by the Oceanographic Institute, both at sea and on major rivers and lakes in the South of Vietnam, have contributed to build a collection of 4,000 individuals at least. Its inventory and the development of a huge documentation allowed the publication of the present note that includes 375 species.

Notes sur quelques poissons d'espèces nouvelles ou peu connues des eaux douces Cambodgiennes

The ichtyological research, conducted in Cambodia from 1938 to 1939 by the Oceanographic Institute, has greatly enriched the Indochinese freshwater wildlife inventory. 40 new species for Indochina were harvested. They have been divided into 12 families and 30 genera, 12 new species for Indochina. The 7 completly unknown species described in this note are: Clupea (Alosa) Thibaudeaui, Xenocheilichthys Loppei, Cosmochilus Pellegrini, Kryptopterus Cheveyi, Pangasius altifrons, Cybium cambodgiensis, Synaptura krempfi.

La Coopérative des Pêcheries d'eau douce du Cambodge

Thanks to the initiative of the Superior Residence of Cambodia and the General Government, a fishery cooperative was founded in late December 1940 in Phnom Penh to ensure proper packaging and direct selling of dry fish. The Cooperative received and treated 10,000 tons of fish. In 1942, the Cooperative directed its efforts towards the Indochinese market and it obtained satisfactory results.

Les batraciens de l'Indochine

This study on batrachians follows two previous works on Indochinese fauna, "Snakes of Indochina" and "Marine turtles of Indochina" by the same author. Hand drawings with all relevant details of every species have been included.

Étude morphologique et physiologique du sang, de l'immunité naturelle et acquise chez quelques poissons Indochinois

This paper deals with a morphological study on blood of some Indochinese freshwater fishes. The study has been split in two parts: one dedicated to compare some fishes' blood and the second part focused on reaction of cells and natural immunity.
