Trough Movement |
 |
| How will the trough develop? Use the matrix below to best describe the evolution of the upper flow pattern over the next 6 hours. |
  |
Yes indeed the trough is sharpening. So what will this mean in terms of development?
|
No. The stronger flow is upwind of the trough and the flow is mainly zonal. This will not result in the trough becoming stationary.
|
No. The flow is mainly zonal it is therefore impossible for the trough to retrogress.
|
As we have discovered the trough is diffluent. A confluent trough is required for relaxation.
|
No. The strong flow on the upwind side the trough will not allow the trough to become stationary.
|
No. The strong flow on the upwind side the trough will not allow the trough to retrogress.
|
No. For the trough to disrupt the southern portion of a trough would advance, perhaps developing a cut-off circulation, whilst the opposite (residual) portion of the trough becomes quasi-stationary.

|
Yes, the trough will extend and progress.
|
No. The strong flow on the upwind side of the trough means it is unlikely to become stationary.

No. the flow is mainly zonal it is therefore imposible for the trough to retrogress.
