| Abstract | Precipitation is a critical element of the climate of the Southern Hemisphere (SH), and observations of its mean annual cycle and interannual variability are crucial to understanding SH climate variability. Twenty-two years ago, at the time of the first Conference on Southern Hemisphere Meteorology in Sao Jose dos Campos, Brazil, our knowledge of SH precipitation over land was based on rain gauge observations, yielding climatologies with excellent detail but with much less information on year-to-year variability. Over the Southern Ocean (SO) the situation was even less satisfactory, as our knowledge was limited to climatologies based on a variety of limited information, including ship observations of present weather and island rain gauges; no time series of precipitation analyses existed. Linking land and oceanic precipitation variability was essentially impossible aside from some limited information that was available from convective indices based on infrared satellite observations for the tropics and subtropics. At the present, we have global time series of analyses of monthly and pentad precipitation from the Global Precipitation Climatology Project (GPCP) and CPC Merged Analysis of Precipitation (CMAP), both based on the combination of information from passive microwave and infrared sensors on both polar orbiting and geostationary satellites. We also have powerful new observations, including those from the Tropical Rainfall Measuring Mission, as well as new algorithms capable of deriving high resolution precipitation analyses for much of the globe. These multiple data sets have proven useful for a wide variety of climate studies, from the description of intraseasonal and interannual variability to the validation of global weather and climate forecast models. However, a number of major concerns exist with these data sets. The global analyses of the GPCP and CMAP have significant inadequacies, including inhomogeneities in input data and methodology, temporal and spatial artifacts, the inability to clearly define decadal and longer variability and a failure to adequately resolve the global water and energy budgets. To a substantial extent, these issues arise from gaps and changes in the global observing system, such as the advent of passive microwave observations in mid-1987 and the continued development of such instruments, the availability of the TRMM radar since late 1997, and the evolution of the global geostationary satellite network since 1980. In this paper, we will describe the mean annual cycle and interannual variability in SO precipitation as depicted in the GPCP and CMAP, and attempt to identify the robust findings as well as the ambiguities and shortcomings. We will examine the finer scale detail in regions of interest using the newer finer resolution datasets such as the TRMM RT and CMORPH, and will describe the initial results of the Pilot Evaluation of High Resolution Precipitation Products, an international collaboration involving producers and users of precipitation datasets using satellite and in situ observations. | |||
