We also complained to our Dispatchers about the loss of information. Thats the official story:
In accordance with the implementation of ICAO Annex 3 Amendment 74 (effective 7th November 2007) the depiction of surface fronts, the inter-tropical convergence zone and cloud on SWM forecasts issued by WAFC London and WAFC Washington changed. Under Amendment 74 recommendations, for SWM forecast data, the WAFCs were no longer required to:
i) depict surface fronts;
ii) depict the inter-tropical convergence zone (ITCZ)s; and
iii) indicate non-CB cloud type or amount. Reference will therefore only be made to the degree of CB activity or in-cloud icing and turbulence.
As all worldwide available Aviation WX-Charts are produced by the UK Met Office, there is no short term solution to bring the information back into official documenation. However it is being reviewed, if any other publicly availiable WX-Charts containing frontal information can be delivered supllementing the standard briefing package.
