چکیده
Abstract. The sea level over the tropical Pacific is a key indicator reflecting vertically integrated heat distribution ocean. Here, we use Geophysical Fluid Dynamics Laboratory global ocean–sea ice model (GFDL-OM4) forced by both Coordinated Ocean-Ice Reference Experiment (CORE) and Japanese 55-year Reanalysis (JRA-55)-based surface dataset for driving models (JRA55-do) atmospheric states (Ocean Model Intercomparison Project (OMIP) versions I II) to evaluate performance biases compared against available observations. We find persisting mean state dynamic (DSL) bias along 9∘ N even with updated wind forcing in JRA55-do relative CORE. related stress geostrophic currents 4 latitudinal band. simulation significantly reduces DSL trend northern In CORE forcing, anomalous westerly eastern causes an underestimated across entire basin 10∘ N. also identify easterly 20∘ CORE, thus motivating future improvement. JRA55-do, accurate Rossby wave initiated at seasonal timescale corrects biased variability of equatorial countercurrent simulation. Both generate realistic variation during El Niño. asymmetry pattern on two sides Equator strongly curl that follows pressure evolution

این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...

THIS panel was developed to quantify natural killer (NK) cell subsets in Rhesus macaques (Macaca mulatta) during SIVmac239 infection induced pathogenesis. It includes markers to monitor changes in the activation/proliferation phenotype of up to 12 NK cell populations. The performance of the staining was tested on cryopreserved lymph node samples, and on fresh and cryopreserved peripheral blood ...
متن کاملFuture extreme sea level seesaws in the tropical Pacific.
Global mean sea levels are projected to gradually rise in response to greenhouse warming. However, on shorter time scales, modes of natural climate variability in the Pacific, such as the El Niño-Southern Oscillation (ENSO), can affect regional sea level variability and extremes, with considerable impacts on coastal ecosystems and island nations. How these shorter-term sea level fluctuations wi...
متن کاملSea-level rise at tropical Pacific and Indian Ocean islands
Historical and projected sea-levels for islands in the tropical Pacific and Indian oceans are a subject of considerable interest and some controversy. The large variability (e.g. El Niño) signals and the shortness of many of the individual tide-gauge records contribute to uncertainty of historical rates of sea-level rise. Here, we determine rates of sea-level rise from tide gauges in the region...
