Many papers show that the rhytms take an important part in long-range weather forecasting. The rhythms appear in wide band of spectrum varying, from two months to eleven months, but the most dominant is the half year rhythm.Investigations on the development of similarities between two monthly mean circulation maps in the Northern Hemisphere or between two sea surface temperature maps in North Pacific and North Atlantic proved the realities of the rhythm activities. For example, if the sea surface temperature...

Many papers show that the rhytms take an important part in long-range weather forecasting. The rhythms appear in wide band of spectrum varying, from two months to eleven months, but the most dominant is the half year rhythm.Investigations on the development of similarities between two monthly mean circulation maps in the Northern Hemisphere or between two sea surface temperature maps in North Pacific and North Atlantic proved the realities of the rhythm activities. For example, if the sea surface temperature anomalies are similar for two months in spring or summer, then they usually get some similarity in both following autumn or winter. Atmospheric circulation anomalies in summer are formed under the influence of atmospheric circulation anomalies in the past three and four seasons.Two kinds of mechanism controlling rhythms were proposed. The first, summer sea surface temperature in the westerly drift current in the North Pacific can give some influence on the winter sea surface temperature, and then on the atmospheric circulation and weather. The second, both sea surface temperature and atmospheric circulation in the low latitudes at east part of North Pacific in winter act as forcing factors to the atmospheric circulation in the following summer.

本文讨论了对长期天气预报比较重要的韵律问题,共有三部分内容:(1)分析广大台站在相关普查中发现的隔季相关现象,相关间隔自2个月到11个月不等,其中大约半年左右的比较常见,并且地理分布区域性强,大洋上最明显,指出这是韵律现象。 (2)月平均环流与海温的相似性分析表明,北半球环流与海温都存在着隔季相似性。例如,春或夏海温距平相似时,大约6个月之后又相似。而秋冬春三季大气环流的相似容易造成夏季大气环流的相似。指出这是大气环流与海洋的韵律活动的表现。 (3)讨论了两种可能的韵律形成过程,一种是北太平洋西风漂流区夏季海温通过韵律关系影响半年后的冬季海温,从而影响大气环流和天气。另一种是冬季低纬东太平洋海温与大气环流相互作用,通过韵律关系影响半年之后夏季低纬太平洋的环流,从而影响西太平洋副高及我国天气。

The formation of anomalies of monthly mean atmospheric circulation was examined in relation to the interactions between the atmosphere and sea-surface temperature. It is indicated that in the current regions the ocean as a heat source exerts an deep influence on the formation of the anomalies of atmospheric circulation. But in the un-current regions thermal regime of the oceans are controlled by the atmospheric circulation.The persistence of anomalies of the atmospheric circulation was investigated. It has been...

The formation of anomalies of monthly mean atmospheric circulation was examined in relation to the interactions between the atmosphere and sea-surface temperature. It is indicated that in the current regions the ocean as a heat source exerts an deep influence on the formation of the anomalies of atmospheric circulation. But in the un-current regions thermal regime of the oceans are controlled by the atmospheric circulation.The persistence of anomalies of the atmospheric circulation was investigated. It has been found that in the temperate latitudes there are two minima in the annual course of persistence at Spring and Autumn. It is shown that March-April and September-October minima of persistence are very closely connected with the two maxima in the annual course of variation of heat source and sinks. In the lower latitudes there is only one minimum of persistence in the annual course. Analysis indicated that it may have some link with the annual variation of intensities of heat source over the Kuro-shio.The investigation of natural analogies showed that when the circulation or sea surface temperature anomalies for two month had similar characteristics, then the following months also had some similarity, but the similarity did not decreased monotonously with increasing of the time interval. In the 4 th to 5 th month or in the 9 th to 11 th month apart from the beginning the similarity was much bigger than preceding and following months. From results mentioned above, it may conclude that only this very rhythm in atmosphere and ocean, indeed, makes the long-range weather forecasting possible.

首先,讨论了环流异常的形成与海气相互作用的关系。指出在明显洋流区,尤其是暖洋流区,海洋为热源,对环流异常的形成有重要影响。在大洋中部的非洋流区,更大程度上是海洋热状况受大气环流控制。 其次,研究了环流异常的持续性。发现中纬度3—4月及9—10月有两次持续性的最低点,并且指出,这与冷热源的月际变化在春秋期间最大有关。但在低纬度,尤其在大洋上的暖洋流区,一年中只有一次持续性最低点,发生在夏末秋初。分析表明,这与那里冷热源强度的年变程有关。 最后,根据相似分析,讨论了环流及海温异常变化的韵律性问题。发现当两个月的环流异常相似时,以后并不是随着时间的推移相似性愈来愈小,而是在相隔4—5个月及9—11个月时相似性较大。这种大气与海洋的韵律活动在长期预报中有重要作用。

The power spectra of the zonal harmonic coefficients show that the quasi-periodic oscillations such as "Index Cycle", half-year rhythm and seasonal variation are predominant. In terms of these quasi-periodic oscillations, a statistical forecast scheme has been designed, with which a set of eight successive pentad mean height forecast at 500 mb level over the Northern Hemisphere can be made. The results of sixty sets of forecasts for the period from 1976 throughout 1980 indicate that the mean forecast accuracy...

The power spectra of the zonal harmonic coefficients show that the quasi-periodic oscillations such as "Index Cycle", half-year rhythm and seasonal variation are predominant. In terms of these quasi-periodic oscillations, a statistical forecast scheme has been designed, with which a set of eight successive pentad mean height forecast at 500 mb level over the Northern Hemisphere can be made. The results of sixty sets of forecasts for the period from 1976 throughout 1980 indicate that the mean forecast accuracy for the sign of deviations fromthe latitude average, ρ=n+-n-/N , is approximately 0.22,and for the sign of the anomalies from the climatic average givesρ=0.08.

本文应用谐波分析和功率谱分析方法,计算分析了1951—1970年北半球500毫巴多年候平均图和1975—1980年40°N、60°N 500毫巴逐候的候平均高度值。发现逐候的各谐波系数序列,除具有气候季节变化趋势外,还具有“指数循环”时间尺度及多种韵律活动准周期性振荡的特征。 利用这一特征,设计了一个用周期外延叠加的预报方案。每次接连预报未来8个候的北半球500毫巴候平均高度。对1976—1980年60个月40°N和60°N两纬圈进行预报试验。效果检验表明,本预报方案有一定预报价值。它对纬圈偏差符号的预报准确率平均达ρ=0.22,对气候距平符号的预报准确率平均为ρ=0.08。
