Further, we investigated the possible impact of SDP on ENSO event in interannual scale by researching the anomalous characteristics of sea temperature, wind, convergence and divergence, total cloud amount, radiation and so on. The results showed that the influence of SDP on ENSO involve not only the process of positive and negative air-sea feedback, but also the interaction between atmospheric circulation over tropical and subtropical, specially the eastward propagation of anomalous zonal wind from the equatorial Indian Ocean to the Pacific Ocean. Otherwise, it also relates, to some extent, to the transition of large-scale climatic mean flow over the Indian Ocean and Pacific Ocean.

进一步,本文通过分析SDP事件前后期海温、高低层风、低层辐合辐散、高空云量和辐射等的变化特征研究了南印度洋偶极型海温异常在ENSO事件中的作用,结果表明:SDP在ENSO事件中的作用不仅涉及海气相互作用的正负反馈过程,还与热带和副热带大气环流之间的相互作用有关,特别是与东南印度洋海温变化所引起的异常纬向风由赤道印度洋向赤道太平洋传播的过程等有十分直接的关系;同时,SDP对ENSO事件的影响在很大程度上还依赖于大尺度平均气流随季节的变换。

The south and north of the windward side of the Annam Cordillera show great difference in the diurnal variation of rainfall, which is related to migration of rainfall. Rainfall over coastal areas of the Thailand Gulf in 01-04LST migrates to inland northeastwards and then heavy rainfall occurs over areas southwest of the Annam Cordillera in 16-19LST, after that heavy rainfall migrates northwestward along the Annam Cordillera to areas northwest of the Annam Cordillera in 01-04LST in the next day. The migration of rainfall results in different characteristics of diurnal variation on the windward side of Annam Cordillera.

长山山脉西侧迎风坡的一南一北两个区域,表现出明显不同的降水日变化特征,其原因与降水的传播有关。01-04LST,降水大值区出现在泰国湾东部沿海,并向中南半岛岛内传播,16-19LST在长山山脉西南侧形成降水大值区,之后降水进一步沿山脉向西北传播,并于次日01-04LST传到长山山脉西北侧区域,通过降水的这种传播特征从而导致长山山脉迎风坡一侧不同的降水日变化特征。

And the results indicate that the principal stress directions in study area are mainly NE-SW, and the second substage tectonic twist made the direction deflect from North to East, but the primary direction changed little; tectonic activities during the O〓~S~D stage is some violent, most of the area are under high stresses status, and rock fracture degree is correspondingly higher, as coinciding with the drill cores observation, i.

通过数值分析,模拟了塔中Ⅰ号断裂带和塔中45井三维模拟区O〓灰岩的构造应力场和应变场,结果表明:研究区主应力方向为北东~南西向,第二期的构造扭动使其由北向东发生了一定的偏转,但总的方位变化不大;O〓~S~D时期,塔中地区构造运动较强,研究区大部分处于高应力状态,岩石破裂程度较高,而岩芯观察结果也证实了这一结果,即O〓灰岩地层中早期形成的构造结构面比较发育,单个结构面的规模也较大;C~P时期,岩石的破坏程度较早期有所提高,主要表现在两个方面,一是各局部区岩石的破坏程度普遍有所提高;二是各个级别破裂区的分布范围相应地扩大了;研究区应力分布表现出明显的不均匀性,特别是剪应力,无论是O〓~S~D时期,还是C~P时期,都有很大的差异性,特别是在小断层的端部,剪应力比较集中,而且在断层的两盘,剪应力方向和大小都变化极快。

Lithologies are mostly sand and carbonate rocks, caps are mud rock, shale and magmatite. Entrap types are anticline, fault block rebuilt by breaking and the screened entrap diapered rock mass. The composition is CO_2, N_2, CH_4, C_2H_6 and He etc. It is magma air source body and its geologic fashions are intrusion and buried volcanic conduit. The relations between gas reservoirs and gas source bodies have three types: magma intrusion-breaking-communicated gas reservoir, magma intrusion-contacted CO_2 reservoir and buried volcanic conduit-contacted gas reservoir. The CO_2 migration in magma intrusion is consisted of fusing and crystallizing phases;it in volcanic conduit is consisted of near-surface effusion and crystallizing phases.The buoyancy of CO_2 in water far more than migration resistance in breaking or chink, CO_2 is easy float upward, the floating can results in differentiation of different density gases and concentration of sealed gas. The gas in sand reservoir firstly migrate into the higher porosity and coefficient of permeability sand, and along with the pressure going up it migrate into the lower. In magma intrusion-breaking-reservoir migration, CO_2 firstly migrate into watered breaking, began gravity differentiation and concentrate, the gas pressure time and again go up, CO_2 migrate into reservoir and concentrate under expansibility as the pressure reach upward a given extend. The CO_2 in reservoir experience four breaking modes: chemistry deposition, dissolution, diffusion and mechanic breaking, the pressure balance can be broken by faulting and the CO_2 will further migrate and form new reservoir.

济阳坳陷已发现的八里泊、阳25、平方王、平南、高青、花17 CO_2气藏主要储集层位有奥陶系、中生界、沙四段、沙三段、沙一段、馆陶组和明化镇组,储集层岩性以砂岩和碳酸盐岩为主,盖层以泥质岩、页岩和岩浆岩为主。;圈闭类型主要为受断裂改造的背斜、断块及刺穿岩体遮挡圈闭。;气体成分主要有CO_2、N_2、CH_4、C_2H_6、He等。;主要气源体为岩浆气源体,气源体的主要地质形式为侵入体和埋藏的火山通道。;气藏和气源体的空间关系有岩浆侵入体一断裂一气藏沟通型、岩浆侵入体-CO_2气储集层接触型和埋藏火山通道-气储集层接触型三种类型。;岩浆侵入体CO_2气运移分为熔融运移阶段和结晶运移阶段,火山通道中CO_2气运移分成近地表喷发阶段和结晶运移阶段。;断裂中,CO_2在水中的浮力远大于运移阻力,CO_2气容易上浮,CO_2在断裂中的易浮性导致不同密度气体的分异和走向上封闭的断裂气体相对富集。;气体在砂岩储集层运移聚集具有选择性,会优先进入孔隙度和渗透率较高的砂岩,随着压力增加,才会进入孔隙度和渗透率较低的砂岩;在岩浆气源体-断裂-储集层空间输导格架下,CO_2气在膨胀力的驱动下,首先进入含水的断裂并重力分异而聚集,气体压力会不断增高,当压力增至一定程度,CO_2气会向高孔隙度、渗透率的储集层运移并聚集。;在岩浆气源体-储集层接触空间输导格架下,CO_2气受膨胀力的驱动直接向储集层运移并聚集。;成藏的CO_2气会经历化学沉淀、溶解、扩散和机械破坏四种破坏方式,会受断裂切割而打破压力平衡,沿断裂进一步运移和聚集成藏。
