With global warming and declining Arctic sea ice area in autumn observed by satellites since 1979, anomalous cold snaps in recent winters have affected large parts of North America, Europe, and East Asia. In January 2015, North America suffered extremely cold and heavy snowfall events. As revealed in this paper, the NCEP reanalysis data show that the temperature decreased significantly in January 2015 in North America, including the air temperature in the troposphere and the surface air temperature. Moreover, snow cover increased obviously in January 2015 in North America, while there was a significant negative anomaly of geopotential height. The wind formed the anomalous pattern, which favored cold currents blowing to the North American continent from the polar region, and bringing plenty of water vapor. Our results suggest that the anomalous north wind and decreasing westerly jet stream, which allowed cold and moist air to easily penetrate the North American continent from the Arctic, was one of the main reasons for the extremely cold and heavysnow winter of 2015 in North America.

In this paper, we present a simple spring-block model for ocean internal waves based on the self-organized criticality （SOC）. The oscillations of the water blocks in the model display power-law behavior with an exponent of -2 in the frequency domain, which is similar to the current and sea water temperature spectra in the actual ocean and the universal Garrett and Munk deep ocean internal wave model [Geophysical Fluid Dynamics 2 （1972） 225; J. Geophys. Res. 80 （1975） 291]. The influence of the ratio of the driving force to the spring coefficient to SOC behaviors in the model is also discussed.

Ocean mode (or quasigeostrophic wave) analysis is one of the key data processing technique in oceanic acoustic tomography experiment. A primary study on its application foreground in Navy Oceanography is put forward with CTD data and Carton oceanic assimilation data. It shows that the sound speed mode is not well orthogonal to each other, so that it is practically no use. However, the current mode calculated from the CTD data collected in summer as the position with weak stochastic processes and strong geostrophic balance is well orthogonal to each other, it can be used everywhere in the ocean of the similar water mass at any time as long as the basic condition serves. It can be used for decomposition and reconstruction of dynamic or quasi-dynamic factors such as seawater temperature, from which and average of salinity the sound speed profile can be composed. It also shows that the monthly James Carton assimilation data is well consistent with observation ones in subsurface layer in the region with weak current speed but not well below subsurface layer or near the Kuroshio in the western Pacific. By running a nested ocean general circulation model with adjusted vertical eddy diffusivity to do data assimilation again and applying current mode analysis to reconstruct or compose related factors, it is hopefully possible to improve the precision and space resolution of the oceanic assimilation data. So that, it is definitely possible to obtain the three dimensional high resolution distribution of ocean sound speed in real time with the satellite SST and surface wind fields only.

Using Ensemble Adjustment Kalman Filter(EAKF), two types of ocean satellite datasets were assimilated into the First Institute of Oceanography Earth System Model(FIO-ESM), v1.0. One control experiment without data assimilation and four assimilation experiments were conducted. All the experiments were ensemble runs for 1-year period and each ensemble started from different initial conditions. One assimilation experiment was designed to assimilate sea level anomaly(SLA); another, to assimilate sea surface temperature(SST); and the other two assimilation experiments were designed to assimilate both SLA and SST but in different orders. To examine the effects of data assimilation, all the results were compared with an objective analysis dataset of EN3. Different from the ocean model without coupling, the momentum and heat fluxes were calculated via air-sea coupling in FIO-ESM, which makes the relations among variables closer to the reality. The outputs after the assimilation of satellite data were improved on the whole, especially at depth shallower than 1000 m. The effects due to the assimilation of different kinds of satellite datasets were somewhat different. The improvement due to SST assimilation was greater near the surface, while the improvement due to SLA assimilation was relatively great in the subsurface. The results after the assimilation of both SLA and SST were much better than those only assimilated one kind of dataset, but the difference due to the assimilation order of the two kinds of datasets was not significant.

Classifying and ranking the huge amounts of landscape planning works of urban wetland park is always difficult due to the multi-functions （ecological, leisure, educational and disaster prevention） of the urban wetland park. Therefore, an optimizing rank system is urgently needed. Analytic Hierarchy Process （AHP） and Technique for Order Preference by Similarity to Ideal Solution （TOPSIS） models were used to rank the planning works of 30 urban wetland park based on four mainly factors, which included landscape ecological planning, landscape planning, ecological planning and economic planning. The study indicated that the AHP- TOPSIS model had good discrimination in the classification and ranking of landscape planning works of urban wetland park and it was also applicable to the planning works of other urban greenbelts.

Based on a 3-D dynamic numerical model of primitive equation, the general circulation in the East China Sea and the Yellow Sea was studied with a 0.25 ° ×0.25 ° horizontal grid and a realistic bottom topography. The tidal current and Kuroshio (Japan current) were considered. The main results of the general circulation in the East China Sea and the Yellow Sea were obtained. The numerical results were compared with the observed results. The compared results show that 3-D dynamic numerical model is efficient to predict general circulation in the East China Sea and the Yellow Sea.

A three dimensional baroclinic model (POM) is employed to study the path, orgin and strength of the Yellow Sea Warm Current (YSWC). The model produced results are compared with the observed temperature and salinity fields, the trajectories of drifters and moored current meter data. The results show: (1) It is indicated for the first time that the YSWC in winter orignates from the middle sector (28°N, 126°E), the truning directional sector (30°N, 127°E) of the Kuroshio in the East China Sea (ECS) and the separated sector of the Tsushima Warm Current (TsWC) at (31°N, 128°E), while in summer mainly originates from the Taiwan Warm Current (TaWC) and partly from the separated sector of the TsWC. This path is consistent with the main distribution feature of the quasi synoptic observed temperature and salinity. The model produced anticyclonic gyre (28°N, 125.5°E) branched from the middle sector of the ECS Kuroshio agrees with the observed results of the satellite drifters. (2) The model produced YSWC is located between 50～60m isobath on the West Side of the Yellow Sea Trough (YST), which is consistent with the location of the Warm and Saline tongue. The model produced cyclonic gyre centering at (36°N, 124.5°E) coincides with the observed results in Feb. 1997. The traditional view indicates that the Northern Jiangsu Coastal Current (NJCC) turns eastward at (32.5°N, 122°E). However, we think that the NJCC goes southward and only the coastal water invades near (32.5°N, 122°E). The model produced path is consistent with the warm tongue in the range of 34° 35°N, 122.5° 123.5°E in 30m layer. (3) The model produced YSWC is strong in winter and weak in summer, which coincides with the observations. The northward volume transport along 35°N section in winter and summer are 0.72sv and 0.38sv, respectively, with an annual flux of about 1.54·10 13 m 3. The volume transport entering the Bohai Sea in winter and summer are 0.19sv and 0.09sv, respectively, with an annual fl
