Skill Assessment of North American Multi-Models Ensemble (NMME) for June-September (JJAS) Seasonal Rainfall over Ethiopia

In recent years, there has been increasing demand for high-resolution seasonal climate forecasts at sufficient lead times to allow response planning from users in agriculture, hydrology, disaster risk management, and health, among others. This paper examines the forecasting skill of the North American Multi-model Ensemble (NMME) over Ethiopia during the June to September (JJAS) season. The NMME, one of the multi-model seasonal forecasting systems, regularly generates monthly seasonal rainfall forecasts over the globe with 0.5 - 11.5 months lead time. The skill and predictability of seasonal rainfall are assessed using 28 years of hindcast data from the NMME models. The forecast skill is quantified using canonical correlation analysis (CCA) and root mean square error. The results show that the NMME models capture the JJAS seasonal rainfall over central, northern, and northeastern parts of Ethiopia while exhibiting weak or limited skill across western and southwestern Ethiopia. The performance of each model in predicting the JJAS seasonal rainfall is variable, showing greater skill in predicting dry conditions. Overall, the performance of the multi-model ensemble was not consistently better than any single ensemble member. The correlation of observed and predicted seasonal rainfall for the better performing models—GFDL-CM2p5-FLOR-A06, CMC2-CanCM4, GFDL-CM2p5-FLOR-B01 and NASA-GMAO-062012—is 0.68, 0.58, 0.52, and 0.5, respectively. The COLA-RSMAS-CCSM4, CMC1- CanCM3 and NCEP-CFSv2 models exhibit less skill, with correlations less than 0.4. In general, the NMME offers

Bioactivity of essential oils of local plants against adult <i>Anopheles arabiensis</i>(Diptera: Culicidae) in Ethiopia

引用

Advances in Bioscience and Biotechnology 2013年第8期4卷 805-809页

作者： Fekadu Massebo Mekuria Tadesse Meshesha Balkew teshome Gebre-Michael Aklilu lemma Institute of Pathobiology Addis Ababa University Addis Ababa Ethiopia Department of Biology Arba Minch University Arba Minch Ethiopia Essential Oil Research Centre Ethiopian Institute of Agricultural Research Addis Ababa Ethiopia

The adulticidal activities of essential oils of eleven plants namely Chenopodium ambrosioides, Eucalyptus citriodora, Eucalyptus globules, Lippia adoensis, Mentha spicata, Nigella sativa, Ocimum lamiifolium, Ocimum suave, Piper nigrum, Schinus molle and Thymus vulgaris were assessed against a laboratory colony of Anopheles arabiensis in Ethiopia. The Centers for Disease Control and Prevention (CDC) glass bottle bioassay was adopted to conduct bioefficacy tests. For each replicate, ten blood-unfed female An. arabiensis were exposed to different concentrations of essential oils coated in glass bottles, and mortality was recorded at intervals of 5 minutes for one hour to assess the mean percentage mortality and LC50 and LC90 values. The residual toxicity of six essential oils was also assessed by exposing adult An. arabiensis in nylon netting Barraud cages treated by oils. Of all the essential oils assessed for adulticidal activities, O. suave was found to be toxic at low concentration (LC50 = of 0.0014 ml% v/v;LC90 = 0.0027 ml% v/v). The next efficacious oil was that of T. vulgaris with LC50 and LC90 values of 0.0028 ml% v/v and 0.005 ml% v/v, respectively. The lowest activity was due to S. molle, E. globulus and P. nigrum. At a concentration of 0.05 ml% v/v, O. suave killed 100% of An. arabiensis within five minutes of exposure, while P. nigrum at the same duration caused similar rate of mortality at a concentration of 50 fold. Residual toxicity tests revealed O. suave to persist for 15 days, killing all mosquitoes in the first five days and 80% up to 10 days. The lowest residual activity was noted for E. citriodora which persisted only for 2 days. The essential oil O. suave acquired the highest level of toxicity at low concentration and within a short time. The efficacious nature of most plants has an implication for more screening of components of these plants with potential adulticides and develops for mosquito control.
