Changes in the metastability of the Southern Hemisphere 500-hPa circulation are examined using both cluster analysis techniques and split-flow blocking indices. The cluster methodology is a purely data-driven approach for parameterization whereby a multiscale approximation to nonstationary dynamical processes is achieved through optimal sequences of locally stationary fast vector autoregressive factor (VARX) processes and some slow (or persistent) hidden process switching between them. Comparison is made with blocking indices commonly used in weather forecasting and climate analysis to identify dynamically relevant metastable regimes in the 500-hPa circulation in both reanalysis and Atmospheric Model Intercomparison Project (AMIP) datasets. The analysis characterizes the metastable regime in both reanalysis and model datasets prior to 1978 as positive and negative phases of a hemispheric midlatitude blocking state with the southern annular mode (SAM) associated with a transition state. Post-1978, the SAM emerges as a true metastable state replacing the negative phase of the hemispheric blocking pattern. The hidden state frequency of occurrences exhibits strong trends. The blocking pattern dominates in the early 1980s, and then gradually decreases. There is a corresponding increase in the SAM frequency of occurrence. This trend is largely evident in the reanalysis summer and spring but was not evident in the AMIP dataset. Further comparison with the split-flow blocking indices reveals a superficial correspondence between the cluster hidden state frequency of occurrences and split-flow indices. Examination of composite states shows that the blocking indices capture splitting of the zonal flow whereas the cluster composites reflect coherent block formation. Differences in blocking climatologies from the respective methods are discussed.
] June 19th news billion state power network, the State Administration for Industry and Commerce issued the "notice on the Administration for Industry and commerce to carry out the 2014 Red Shield network sword special action today on its official website" (hereinafter referred to as the notice), will be on the network and selling trademark infringement action and law enforcement efforts to impose heavy governance.
billion state power network found that the "2014 Red Shield network sword special action is the focus of the fight against Internet sales of counterfeit and shoddy goods and trademark infringement behavior, to the well-known trademark, foreign trademarks, geographical indications as key protection.
It is important to note that
is the focus of the event is target of online trading platform, shopping sites and group purchase website, key regulatory product categories are electronic products, children’s products, auto parts, clothing, cosmetics and agricultural goods.
analysis of the industry, the industry and commerce administration law enforcement is not small, because found illegal business website (shop) may be closed. "Notice" mentioned in the event, to investigate and punish vigorously exposure online sales of fake and shoddy goods important cases, closing a number of illegal business website (shop). At the same time, the use of the network to engage in unfair competition, pyramid schemes, false advertising and other illegal acts of the trade and Industry Bureau severely punished.
billion state power network to understand, "2014 Red Shield network sword special action will be officially launched in July 2014 to November day.
is the following announcement:
SAIC on the development of 2014 Red Shield network sword
special action notice
all provinces, autonomous regions, municipalities directly under the central government and cities under separate state planning, the provincial and Municipal Administration for Industry and Commerce and the market supervision and Administration Bureau:
in recent years, the industrial and commercial administrative organs continue to increase network market rectification, standardize market order network management work step by step, but the Internet sales of counterfeit goods and other illegal activities still occur, the network and selling behavior of some goods is still rampant, must strengthen law enforcement efforts to impose heavy governance. In order to further improve the efficiency of network transaction monitoring, to crack down on the sale of counterfeit goods over the Internet and trademark infringement behavior, effectively deal with problems the concerns of the masses, media attention commodity trading network, strengthen the network commodity trading behavior supervision, net network shopping environment, safeguard the legitimate rights and interests of consumers and business operators, SAIC decided on July 2014 in November to carry out 2014 Red Shield network sword special action. The relevant matters are hereby notified as follows:
first, the working principle of
should fully realize that the network market is an important way to realize the sustained and healthy development of our economy and social harmony and stability. Red Shield network sword special action to adhere to norms and development, remediation and construction and
