Royal Charter (ship) by some passengers, though not confirmed, that the master, Captain Thomas Taylor, was advised to put into Holyhead harbour for shelter. He decided to continue on to Liverpool however. Off Point Lynas the "Royal Charter" tried to pick up the Liverpool pilot, but the wind had now risen to Storm force 10 on the Beaufort scale and the rapidly rising sea made this impossible. During the night of 25/26 October the wind rose to Hurricane force 12 on the Beaufort Scale in what became known as the "Royal Charter gale". As the wind rose its direction changed from E to
Wind atmospheric equations of motion and for making qualitative arguments about the horizontal and vertical distribution of winds. The geostrophic wind component is the result of the balance between Coriolis force and pressure gradient force. It flows parallel to isobars and approximates the flow above the atmospheric boundary layer in the midlatitudes. The thermal wind is the "difference" in the geostrophic wind between two levels in the atmosphere. It exists only in an atmosphere with horizontal temperature gradients. The ageostrophic wind component is the difference between actual and geostrophic wind, which is responsible for air "filling up" cyclones over time. The
