<p>A set of deep-time climate simulations each 10Ma years from 250Ma to PI are conducted by using the NCAR-CESM1.2, for understanding the evolution of the ocean monsoon regions driven by tectonic dynamics over the past 250 million years and exploring its variation mechanisms. In recent years, scientists have proposed the concept of a global monsoon system, which includes not only typical monsoon regions (such as the African monsoon region and South Asian monsoon region), but also the atypical Northwest Pacific Ocean monsoon region. Research on the ocean monsoon is very limited, especially in the field of paleoclimate. The results in this paper show that the horizontal gradients of the thickness of the ocean mixed layer may be more important for the formation of the ocean monsoon than land-sea thermal contrast, which is confirmed by the aquaplanet simulations with various gradients of the ocean mixed-layer thickness. Near the Pacific monsoon region in the northern hemisphere, the thickness of the ocean mixed layer has obvious meridional and zonal gradients, which will correspond to the meridional and zonal thermal contrasts. In addition, there are obvious seasonal reversals in the gradients of the ocean mixed-layer thickness in summer and winter, and the corresponding longitudinal and zonal thermal contrast produce seasonal reversals. Over the past 250 million years, the thickness of the ocean mixed layer on the east side of the Pacific Ocean Basin in the Northern Hemisphere has deepened, and the corresponding ocean monsoon area on the east side of the Pacific Ocean has decreased. The changes in the thickness of the ocean mixed layer are closely related to the changes in the surface wind field. Examining the changes in the atmospheric circulations, we find that the Pacific subtropical high strengthens and extends from east to the west bank of the ocean basin, where the atmospheric low-level anticyclonic circulation causes the ocean surface layer to converge and sink and thus causes the ocean mixed layer to deepen. The changes in the Pacific subtropical high are related to changes in the continental monsoon region. Since the 170Ma, the Pangea supercontinent splits up, causing the supercontinent's inland water vapor to increase, the land monsoon area to increase, and the ocean monsoon area to decrease. According to the "monsoon-desert mechanism" of Rodwell and Hoskins, we can understand the relationship between the strengthening of land monsoon condensation heating and the formation of subtropical high over the western ocean.</p>

The Relationship

The relationship between Vietnam and Australia more and more obviously reveals the beneficiality stemming from the demands and capabilities of the two countries. Both positioned in the valley of the Pacific Ocean, the potential and growth of their relationship remains strong in a world of increasingly global and regional reunion and linkage. Optimizing the beneficiality and most effectively exploiting the potential of both countries in their relationship depend on many factors among which total scientific acknowledgement and appreciation of historical process of the relationship are extremely necessary. When does it originate the Australian policy to Vietnam? Which historical epics has it undergone? What is its evolutionary process? And the like? The answers to these questions are the main contents of this paper. The Vietnamese policy to Australia must be set up on the foundation of proper appreciation of this country’s policy to Vietnam and of total perception on the position of Vietnam toward it, on Vietnam’s benefits and exploiting methods in the relationship with this biggest country in Southern Pacific Ocean, etc.

Abstract The surrounding waters strongly influence the waters of North Maluku. These waters are the entrance gate for ARLINDO, which is directly related to the Pacific Ocean. To produce scientific knowledge, our study aims to determine the influence of oceanographic factors on the distribution of sea surface temperatures (SST) and wind pattern, which affects the rainfall throughout the west monsoon and transitional seasons in the Indonesian region literacy. We used data from ERDDAP, where SST data was processed using Ocean Data View and wind data using WRPLOT. The SST of North Maluku waters during October 2020-April 2021 ranges from 29.1°C-29.8°C, with the highest sea surface temperature, was seen during November-December 2020 and April 2021. The result demonstrates the highest rainfall data was in February 2021 and the dominant winds come from north and west. These winds bring water vapor particles that become convective clouds that increase rainfall in Indonesia, especially in the eastern region. Meanwhile, SST originating from the Pacific Ocean moved due to the Walker Circulation from the east. This further caused the SST from the Pacific Ocean that brought a warm water move towards Indonesian waters.
