<p>        The sub-seasonal characteristics and prediction of rainfall over the South China Sea and surrounding areas during spring-summer transitional season (April-May-June) are investigated using a full set of hindcasts generated by the Dynamic Extended Range Forecast operational system version 2.0 (DERF2.0) of Beijing Climate Center, China Meteorological Administration. The onset and development of Asian summer monsoon and the seasonal migration of rain belt over East Asia can be well depicted by the model hindcasts at various leads. However, there exist considerable differences between model results and observations, and model biases depend not only on lead time, but also on the stage of monsoon evolution. In general, forecast skill drops with increasing lead time, but rises again after lead time becomes longer than 30 days, possibly associated with the effect of slowly-varying forcing or atmospheric variability. An abrupt turning point of bias development appears around mid-May, when bias growths of wind and precipitation exhibit significant changes over the northwestern Pacific and South Asia, especially over the Bay of Bengal and the South China Sea. This abrupt bias change is reasonably captured by the first two modes of multivariate empirical orthogonal function analysis, which reveals several important features associated with the bias change. This analysis may provide useful information for further improving model performance in sub-seasonal rainfall prediction.</p>

Abstract The reversed impacts of the Arctic oscillation (AO) on precipitation over the South China Sea and its surrounding areas (SCSA) in October and November during 1979–2014 are investigated. The correlation coefficients between AO and the precipitation in October and November are 0.44 and − 0.31, which are statistically significant at the 99% and 90% confidence levels, respectively. In October (November), the specific humidity exhibits obvious positive (negative) anomalies in the SCSA, and an upward (downward) airflow moving from ground to the upper troposphere (1000–150 hPa) between 10°N and 30°N (10°N and 20°N) is observed with more (less) cloud cover. Moisture budget diagnosis suggests that the precipitation’s increasing (decreasing) in October (November) mainly contributed by zonal moisture flux convergence (divergence). Furthermore, the Rossby wave guided by westerlies tends to motivate positive geopotential height in the upper troposphere over approximately 20°–30°N, 40°–80°E in October, which is accompanied by a stronger anticyclone in the Arabian Sea region. However, in November, the wave train propagating from the Arabian Sea to the Bay of Bengal is observed in the form of cyclones and anticyclones. Further analysis reveal that the AO in October may increase precipitation through the southern wave train (along the westerly jet stream from North Africa to the Middle East and South China). Moreover, air-sea interactions over the North Pacific might also generate horseshoe-shaped sea surface temperature (SST) anomalies characterized by positive SST in the central subtropical North Pacific surrounded by negative SST, which may affect the precipitation in the SCSA. Ensemble-mean results from CMIP6 historical simulations further confirm these relationships, and the models that can better simulate the observed positive geopotential height in the Arabian Sea present more consistent precipitation’s increasing over the SCSA in October.

Все территориальные споры в Юго-Восточной и Южной Азии в зависимости от их локализации делятся на четыре группы. В первую входят споры, охватывающие территорию бывшей Британской Индии и связанные с нечётко-стью колониальных титулов; во вторую – споры с участием Малайзии, также имеющие колониальный генезис; в третью категорию – споры Японии с её соседями по поводу островов, связанные с нечёткостью послевоенного урегулирования; в четвёртую – споры с участием Китая (помимо споров из первой и третьей групп сюда относится крайне важный спор о принадлежности акватории и сухопутных формирований Южно-Китайского моря). Некоторые из этих споров были разрешены международными судами на основании международного права; к их числу относятся, например, споры о делимитации Бенгальского залива (первая группа). Большинство споров, однако, до сих пор не разрешены, и перспективы правового урегулирования некоторых из них выглядят маловероятными в силу остроты конфликта и сложности историко-правового контекста. Спор о Южно-Китайском море (ЮКМ) является условно-разрешённым: решение по нему было вынесено в 2016 г. Китай, однако, категорически отказался выполнять его. Отношение России к данным тер-риториальным спорам не должно быть пассивным. В отношении споров из первой группы Россия может попробовать вернуться к своей традиционной функции посредника. Конфликты второй группы не затрагивают её интересов; по отношению к ним она должна соблюдать строгий нейтралитет. Что касается конфликтов третьей группы, то Россия сама является их непосредственным участником и поэтому должна предпринимать усилия, направленные на достижение выгодного для неё решения вопроса о Курильских островах. Наконец, применительно к спору о ЮКМ Россия должна встать на сторону Китая, чьи притязания в отношении данной акватории содержательно близки притязаниям России в отношении Арктики. All territorial disputes in Southeast and South Asia are divided into four groups depending on their location. The first group includes the disputes covering the territory of the former British India and provoked by the vagueness of colonial titles. The second group includes the disputes involving Malaysia, which also have a colonial genesis. The third group includes the disputes between Japan and its neighbors over the islands provoked by the vagueness of the post-war settlement. The fourth group includes the disputes involving China, – in addition to the disputes from the first and third groups, this includes an extremely important debate about the ownership of water spaces and land formations of the South China Sea. Some of these disputes have been resolved by international courts under international law; these include, for example, the disputes over the delimitation of the Bay of Bengal (first group). Most disputes, however, are still not resolved and the prospects for legal settlement of some of them seem unlikely due to the severity of the conflict and the complexity of historical and legal contexts. The dispute over the South China Sea is conditionally resolved: a judgment was rendered in 2016, – China, however, categorically refused to comply with it. Russia's attitude to these territorial disputes should not be passive. As for the disputes from the first group, Russia may try to return to its traditional mediator function. The conflicts of the second group do not affect its interests, therefore it must observe a strict neutrality in relation to them. As for the conflicts of the third group, Russia is directly involved in them and therefore should make efforts to achieve an advantageous solution of the Kuril Islands case. Finally, in relation to the South China Sea dispute Russia should support China’s position which is substantially close to Russia's claims in relation to the Arctic.
