ACSOE example trajectory plots


The BADC provides the ACSOE community with plots of clusters of forecast and actual trajectories which are used for planning and analysis purposes. During the 1996 campaigns three air-parcel arrival sites were adopted: Mace Head in South West Ireland; Weybourne off the Norfolk coast and a North Atlantic site representative of the position of the ship. Four different plot formats were used:

  1. PLOT 1: Summary Plot
    Two maps on a single A4 portrait-size page. One map (top) for the centre of the cluster with trajectories arriving at four pressures (700, 850 950 and 1000mb). One map (bottom) for the 1000mb pressure with trajectories arriving at the five horizontal co-ordinates.
  2. PLOT 2: Horizontal variability
    Four maps on a single A4 landscape-size page. One map for each pressure with the trajectories arriving at five horizontal co-ordinates.
  3. PLOT 3: Vertical variability
    Five maps on a single A4 landscape size page. One map for each horizontal co-ordinate with trajectories arriving at four pressures.
  4. PLOT 4: Time series
    Five time series on a single A4 landscape size page. One time series per horizontal co-ordinate showing "pressure height" (inverted log) as a function of time for each arrival pressure.

Example plots showing air-parcel arrival at 12:00 on June 16, 1996 are available for:
