To this end use is made of data from a variety of sources, including web sources, satellite sensors, the South African Weather Service, coastal- and moored instruments and research cruises, and inherent to all of these there is an inevitable lag between the time of data capture and the time when the data first become available for use. The lags are all different. For example, wind data from the Cape Point lighthouse is updated monthly, the moored temperature recorders are serviced every three months and the time series of some satellite data are updated at irregular intervals resulting in lags which may be as long as a year or, in some cases, even several years. Therefore, while it is the aim that the environmental reports should reflect the conditions that prevailed over the months leading up to the reporting date in order to meet the resource management objective, some out-of-date series are incorporated because they provide, for example, information on long-term trends which would otherwise not be available. Also, in addition to observations directly related to local conditions, time series of the Southern Oscillation Index, the South Atlantic high pressure cell and the St Helena Island Index are also provided because they are known, or at least suspected, of representing global and basin scale processes which affect local conditions. |
