... The QBO period is equal to a linear combination of the frequencies corresponding to the doubled periods: of the tidal year (0.97 year ), of the regression of nodes (18.6 years ), and of the motion of perigee ( 8.85 years ) of the Earth's monthly orbit : 1 2 1 1 1 0.97 18.61 8.85 1 2.3 yr (1) In other words, the quasi-biennial oscillation of the wind direction in the equatorial stratosphere is a combined oscillation ...

... This paper discuss a polynomial approximation to T for the range of 1620 to 2000 AD published by Jean Meeus and Larry Simons and gives a modified version of this approximation which is much more accurate. ... For this purpose Jean Meeus and Larry Simons published a paper in 2000, which gives a set of polynomial approximation of T for the range of years 1620 to 2000 (Meeus 2000). ... Using these empirical formulae we can calculate the value of T at any instant of the year for the range 1620 to 2000...

SLIDE 1 Coherent beam­beam e#ects study. ... He has shown that a finite length (in other words equal to # # ) of colliding bunches can lead to the coupling of synchro­betatron modes in the beam­beam system, and thus a head­tail type instability of colliding bunches may arise. ... These modes have been observed in di#erent machines. ... SLIDE 5 Figure shows the dependence of the measured and calculated synchro­betatron mode tunes on the beam current for equal electron and positron bunch intensities. ...
