大気物理研究所で開発された 9 レベル大気大循環モデルを用いて数値実験

大気物理研究所で開発された 9 レベル大気大循環モデルを用いて数値実験の 2 つのセットの東アジア夏季モンスーン循環と東アジアにおける夏季降水量の南部の亜熱帯上 MH と AH の影響を調査するために実行されます。アンサンブルの統計情報の使用をシミュレーション エラーを減らすために採用しています。結果は、MH の強化、熱帯アジアの夏季モンスーン循環とソマリアの下層ジェットが大幅に向上し、フィリピンの東への西太平洋は弱い東アジア太平洋 teleconection パターンを引き起こす可能性がありますを示します。一方で、それは中高緯度のほとんどの地域で減少している間、熱帯地方のジオポテンシャルが強化されて、北西太平洋の亜熱帯高 500hPa を伸ばす南西へ、中国と中国北部の少ない降雨量南部の多くの降雨量の結果します。大気循環システムの同様の異常パターンは AH の激化の実験で発見されます。その一方で、AH に関連付けられている赤道を越えた電流はのでソマリア ジェットより大いに弱い、AH の激化によって引き起こされる異常の大きさは、一般的に弱いと AH の中国での夏の降雨量への影響は中国南部でローカライズされていると思われます。実験の 2 つのセット間の比較は MH の 2 つの hemipheres 間の一般的な大気循環の相互作用に重要な役割を果たしていることを示します。

Performed using the 9-level atmospheric general circulation model was developed by the Institute of atmospheric physics experiments two sets of East Asian summer summer monsoon circulation in East Asia precipitation South subtropical on effects of MH and AH to investigate. Reducing simulation error using the ensemble statistics for adoption. Results the MH enhanced the tropical Asian summer monsoon circulation and Somali Jet significantly and may cause a weak East Asia Pacific teleconection pattern the West Pacific to the East of the Philippines show. On the other hand, results in more rainfall in China and Northern China's less rainfall amount southern to improves the Geopotential Height of the tropics, while it decreased in most areas of the middle and high latitudes, North West Pacific subtropical high 500 hPa to stretch Southwest. As well as abnormal pattern of atmospheric circulation system is found in the experiment of intensification of the AH. On the other hand, current crossed the Equator associated with AH is so considered anomaly caused by the intensification of the much weaker than Somali Jet and AH is generally weak and the impact on rainfall in summer by the China AH localized in southern China. Set between the two experimental comparison indicates that plays an important role in the interaction of the General atmospheric circulation of hemipheres between two of the MH.

In order to investigate the influence of two sets of the East Asian summer monsoon circulation and subtropical on the MH and AH of the southern part of the summer precipitation in East Asia of numerical experiments using a 9-level atmospheric general circulation model that has been developed at the Atmospheric Physics Institute It is run on. Is adopted to reduce the simulation errors using the ensemble statistics. The results, strengthening of MH, tropical improved Asian summer monsoon circulation and Somalia in the lower jet is much, the western Pacific to the east of the Philippines shows can cause a weak East Asia Pacific Ocean teleconection pattern. On the other hand, it is while decreased in most parts of the mid-high latitudes, the tropics of geopotential is strengthening, to the southwest to extend the subtropical high 500hPa of northwest Pacific Ocean, China and northern low rainfall many of southern China I will result of rainfall. Similar abnormal pattern of atmospheric circulation system will be discovered in the experiment of intensification of AH. On the other hand, since the current across the equator that is associated with the AH much weaker Somalia jets, abnormal size caused by the intensified AH is generally weak to summer rainfall in China AH impact of I appears to have been localized in southern China. Comparison between the two sets of experiments indicates that plays an important role in the interaction of the general atmospheric circulation between the two hemipheres of MH.

Developed by the Institute of atmospheric physics is performed by using a model of the atmospheric general circulation level 9 numerical simulation of summer precipitation in the East Asian summer monsoon circulation in East Asia and the southern subtropics is set on the effect of MH and AH survey. Is adopted for the use of ensemble statistics information to reduce the simulation error. The results MH enhanced summer monsoon circulation and tropical Asia is greatly improved in comparison with that of the low level jetShows the Western Pacific Ocean to the East Philippines may cause weak East Asian and Pacific teleconection pattern. On the other hand, while it decreased most in high latitude area, enhanced the tropics geopotential, southwest of the Northwest Pacific subtropical high hPa 500, as a result of China and less rainfall in the southern North China more rainfall. The same system of atmospheric circulation anomaly patterns are found in AH intensified. On the other hand,Current across the equator in the AH associated with Somali jet, so much more vulnerable, caused by the abnormality of AH size is generally weak in China, and AH considered in southern China are localized impact on summer rainfall. Experimental comparison between two sets of the importance of the atmospheric circulation MH hemipheres between two general interaction plays a role.
