Slide 14 of 45
Notes:
Instead of concentrating on a particular height, advances in technology/communications allows us to do assessment of a layer… in this case the 1000-500 hPa layer. The plot shows the mean flow in a vector format. Areas of convergence are contoured in red, while divergence is in blue. The area of convergence overlays the previously mentioned boundary that extends from Rio Grande do Sul to Northwestern Argentina.
