Further Analysis of a Proposed Sun-Weather Relationship

几个世纪以来，人们一直怀疑11年的太阳活动周期对天气的影响，但直到去年才在有把握地描述正在发生的变化方面取得了真正的进展。Labitzke和van Loon的工作表明，在赤道纬度，根据平流层风的方向，这种影响是非常不同的，有必要根据赤道平流层风的振荡阶段对大气数据（风、温度、压力、风暴的位置和频率）进行分类。这些风以两年多一点的周期改变方向，据说经历了“准两年振荡”或QBO，并且已经发现，例如，在QBO的西阶段，北大西洋的风暴路径在太阳极大期比太阳极小期向赤道移动约60度。该奖项是为了对1950年至1987年间170个无线电探空站的对流层风数据进行分析，并根据QBO的阶段进行分类，以评估与太阳活动的相关性强度。希望能够出现特定的变异，从而为了解致病机制的本质提供线索。

The influence of the 11 year solar cycle on weather has been suspected for centuries, but only within the last year has real progress been made on describing with confidence the changes that are occurring. The work of Labitzke and van Loon has shown that the effects are very different depending on the direction of stratospheric winds at equatorial latitudes, and it is necessary to sort the atmospheric data (winds, temperatures, pressures, location and frequency of storms) according to the phase of the oscillation of equatorial stratospheric winds. These winds change direction with a period of a little over two years, and are said to undergo a "quasi-biennial oscillation" or QBO, and it has been found, for instance, that in the West phase of the QBO the storm tracks in the North Atlantic above 50o latitude move equatorward by about 6o at solar maximum as compared to solar minimum. This award is for an analysis of tropospheric wind data from 170 radiosonde stations for the years 1950 through 1987, with sorting according to the phase of the QBO, to evaluate the strength of the correlations with solar activity. Hopefully, specific variations will emerge that will provide a clue as to the nature of the causitive mechanism.
