The severe drought that affects the Sahel since the late 1960s has been very closely studied and monitored during the last three decades. Recently, after several wet years, it was questioned from a statistical point of view whether the drought was over. The conclusions of a recent study were that the rainfall deficit was not over at the end of 2000 and that the drought continues. The analysis of the change points in the station rainfall time series suggests differentiating these findings. There is now growing evidence that there is a potential shift towards a more humid state. However, the present analysis shows that the assumption that a significant increase in rainfall may have occurred around the early 1990s could only be verified at the customary confidence level in about 10 years from now.

The fluctuations of annual precipitation observed in Niamey and Zinder (Niger) since the turn of the century warranted a comparison of rainfall maps and rainy-season characteristics between 1950-1967 (period of high rainfall) and 1968-1985 (period of low rainfall). Calculating two specific annual spatiotemporal rainfall profiles provided precisions as to the irregular and heterogeneous advance of the drought through Niger. [less ▲]

Fisheye pictures are frequently used in forestry and in ecology for canopy measurements. In climatology, it seems that they have only been used for illustration purposes. In fact, fisheye pictures are rich in climatological information. Digital fisheye image processing can be used for applied climatology as well as for topoclimatological studies. It allows the quantification of insolation, diffuse radiation, sky-view factor,.… In other words, it provides an objective assessment of the exposure of a site or of a measuring device. This article introduces the basis for digital fisheye image processing. The possibilities offered by this tool will be illustrated with sunshine measurements in an urban environment. [less ▲]
