<br />~0JO <br /> <br />, <br /> <br />As we were driving over this morning, <br />we saw what appears to be a strong jet <br />stream developing over here right at the <br />present time. When this jet stream devel- <br />ops sudden bends and goes far, far to the <br />south, this produces a completely differ- <br />ent weather regime from the weather regime <br />that we have when this jet stream moves to <br />the north. If the jet stream were to change <br />its average position in the coming fifty <br />years Sb it receded five hundred miles to <br />the north, it would produce a drought the <br />likes of which has never been seen over <br />Colorado. <br /> <br />I <br /> <br />Now we don't, at the present time, <br />know just exactly why this jet stream bends <br />to the south at certain times and why on <br />the average, for example last year, the jet <br />str-eam was about three hundred miles south <br />of the position it had in the 1954 period. <br />We don't know why that was true. This por- <br />tion of the research would attempt to in- <br />vestigate the relationship of the bends of <br />this jet stream on the one hand, the rela- <br />tionship of thi,s to the precipitation data <br />in the second part of the study and the <br />stream flow data in.the first part of the <br />study. It would also try to relate these <br />things back to phenomena outside the earth. <br /> <br />Now it is a very striking thing that <br />the activity of the sun, for example, has <br />changed in the past fifty years very markedly. <br />At the turn of the century there were many <br />fewer sunspots than there have been as we <br />come past the middle of the century, on the <br />average. The eruptions that occur on the <br />face of the sun, like this one of which I <br />brought a photograph along, this sudden out- <br />break here, these have been far more abun- <br />dant in recent years than they were at the <br />turn of the century, and the occurrence of <br />enormous clouds of gas, some of you have <br />seen the movies that we make of these at I <br />Climax. The occurrence of these enormous . <br />prominences, as we call them, shooting out <br />from the sun have become much more frequent <br />in recent years. <br /> <br />It is also true that in recent years we <br />have seen a change, an apparent change in <br />the regime of weather that has resulted in <br />
