β¦ Synopsis
Over the last decade global numerical weather prediction models have become sufficiently sophisticated to forecast the movement of tropical cyclones with a reasonable degree of accuracy. This paper describes the work being done at the Met. Office in Bracknell, UK, to improve and verify track forecasts, looking particularly at methods of 'bogussing' the initial conditions and of verifying the forecasts.

## Abstract In 1994 a new method for the initialisation of tropical cyclones (TCs) was implemented in the Met Office Unified Model (MetUM). In trials this resulted in a 34% drop in track forecast errors. TC track forecast errors in the MetUM have continued to show a modest downward trend since then
## Abstract This study examines the interannual variability of the tropical cyclone (TC) activity in the Southern Hemisphere (SH) during the period 1970β2008. An empirical orthogonal function analysis of the annual frequency of TC occurrence shows three leading modes of TC occurrence patterns. The
## ABSTRACT Highβresolution NWP models which can explicitly allow convection (albeit poorly resolved) are usually run in limitedβarea domains, and are nested inside coarser resolution models with parametrized convection. The mismatch of the grids and model physics at the boundaries of the limitedβa
## Abstract The interannual variability of tropical cyclone (TC) movement has been found to be rather significant in certain regions of the western North Pacific. Westward and northwestward moving TCs are found to occur mostly at low latitudes and have the largest interannual variations in the regi
