 Forcing the Circumglobal Teleconnection pattern\n\nWhen the South Asian je
 t is in a particular phase\, there exists a circumglobal teleconnection pa
 ttern (CGT) whereby circulation disturbances originating near the jet entr
 ance\, or within the jet\, remain trapped and can propagate around the glo
 be. Recent studies have shown that this CGT pattern is associated with con
 vection in the vicinity of India\; however the cause-effect relationship r
 emains unclear. This study aims to elucidate whether the CGT can be forced
  to occur given a convective anomaly near this location\, or if this conve
 ctive activity is simply the result of the CGT. We use both reanalysis dat
 a\, and linear model results to determine whether this\, or any other trop
 ical convective forcing can induce this circumglobal pattern. By running t
 he model multiple times with a forcing induced at a different location eac
 h time\, we can construct a map of locations likely to force the CGT. We c
 an then support these results using lagged composites from reanalysis data
 . Our results show that not only does a forcing in the Indian Ocean induce
  this pattern\, but convective anomalies elsewhere in the Tropics result i
 n circulation anomalies that also resemble the CGT.\n\nWednesday Nov 13/ 2
