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.
for investors, no matter what time investment in the jewelry industry will not become obsolete, at the same time, every year people for jewelry demand is also increasing, you know, in the jewelry industry, jewelry display is one of the important factors affecting sales.
An important task in material management of
although the jewelry counter placed much can be freely determined, but are not good will directly affect sales. For example, put too much not only takes money, will also appear in chaos because of its vertigo and make customer hesitate in the selection; put too little although saving money, but make the customer the choice of small, unforeseen purchase will peak because of the goods shortage and missed business opportunities; there is a goods display too little for the mall does not agree, because of the large shopping malls usually require the counter of the goods can not be too small, but also so the counter in the jewelry number placed there is an optimal problem.
counter jewelry varieties
mainly involves two aspects: the type of jewelry and gemstones. There is also a problem of quantity and proportion in these two aspects, and the proportion is more important. At present, the domestic sales of jewelry chain market is mainly diamond jewelry, because the propaganda is not enough people know little about other gems, and followed by a small amount of ruby, sapphire, emerald, pearl jewelry, and other precious stones is even more scarce.
should be adjusted according to the seasons like national day before and after put ring for the proportion of various types of jewelry; the spring and autumn season of multi swing necklaces, earrings, earrings and brand chain; according to the seasons change. So we should adjust the goods to adapt to changes in the market, enterprises can also have the best suggestion jewelry counters this season in the north and the South can transform north and south to adjust without new products or once had to date next year to sell to inventory.
there is to separate them for the special goods. For example, this season, the main push series, special offers, etc.. Do have the main time, highlight the main want to sell goods.
