The following images were prepared by Robert L. Molinari and John F. Festa of AOML in support of the WOCE South Atlantic Workshop
These show the amplitude and phase of the annual harmonic. These are given as arrows with lengths proportional to the amplitude of this harmonic and direction proportional to the phase. Inset arrows provide the scale and have a length of 2C and phase in months indicated as 1 = 1 January, 4 = 1 April, etc. Arrows are only given for those grid points with more than 3 bimonthly values of data.
