This study is aimed at improving rainfall prediction using ensemble methods. It first assesses the performance of six convective schemes (Kain–Fritsch (KF); Betts–Miller–Janji´c (BMJ); Grell–Fretas (GF); Grell 3D ensemble (G3); New–Tiedke (NT) and Grell–Devenyi (GD)) using the root mean square error (RMSE) and mean error (ME) focusing on the March–May 2013 rainfall period over Uganda. 18 ensemble members are generated from the three best performing convective schemes (i.e. KF, GF & G3). The performance of three ensemble methods (i.e. ensemble mean (EM); ensemble mean analogue (EMA) and multi–member analogue ensemble (MAEM)) is also analyzed using the RMSE and ME. The EM presented a smaller RMSE compared to individual schemes (EM:10.02; KF:23.96; BMJ:26.04; GF:25.85; G3:24...

In these regions, urban and peri-urban agriculture (UPA) plays an important role in helping to provide diverse urban diets and environmental services. As such, there is growing interest in UPA as a strategic component of urban resilience and climate change adaptation planning. However, advocacy for UPA in this capacity is outpacing the body of evidence regarding important stressors and drivers that act on UPA. Such knowledge is especially critical in the developing world where urban areas are experiencing rapid growth and transformation. In these regions, UPA is facing intensifying pressures from urban encroachment, waste disposal, pollution, and climate change that may undermine the sector's long-term viability. The need to better understand these critical sustainability dimensions provided the impetus for city-level knowledge assessments of UPA, whose main fin...

The monthly rainfall records for the years 1961 -1990 inclusive at 150 raingauge stations used in the study were extracted from the records at the Directorate of Meteorology, Tanzania. The spatial patterns of the rotated PCA dominant modes delineated Tanzania's raingauge network into 15 homogeneous groups. Statistical tests, climatological information, topographic features and other data supported the physical reality of the 15 delineated groups. The delimited rainfall regions may be useful for Tanzania in agricultural planning, the assessment of water resources potential, delineation of drought or flood risk zones and as a basis of ensuring collection of climatologically representative rainfall data by the inclusion of a station(s) from each homogeneous rainfall region.

ABSTRACT Abstract Diurnal variations in the total electron content (TEC) at Makerere University (... more ABSTRACT Abstract Diurnal variations in the total electron content (TEC) at Makerere University (00°19′N, 32°40′E, Geo Dip −22°), Uganda, have been investigated using a NovAtel GSV400B GPS receiver for the year 2010. The highest TEC values occurred from 13h00 to 17h00 local time (LT) throughout the year, with the highest values being exhibited during equinoctial months. In addition, there was some correlation between this high TEC and the moderate storms that occurred in 2010. These high TEC values have been attributed to the solar EUV ionization coupled with the upward vertical ExB drift. Nighttime enhancements were also found to be seasonally dependant, attaining maximum values during equinoctial months. These results were also compared with modeled TEC values by the IRI-2007 model. The modeled values were in good agreement with the measured values except for these two points: (1) the model had a short-fall in predicting the nighttime enhancements; and (2) the model’s minimum TEC did not coincide with the measured minimum in most of the months. Observed TEC depletions were found to correlate with an increase in the S4 index and have been identified as a manifestation of the plasma density depletions of the equatorial origin.
