Whole territory of Ethiopia is located in equatorial and subequatorial climate zones however altitude variety brings some features to weather conditions of the country. Given their spatial distrib, these data can be considered suitable only for a climatic, point characterization and as a baseline, though some sta-, tions may have changed location and instrumentation, to, study climate variations, if any, but do not allow to de, In Ethiopia, most of the longest rainfall and temperature, records began in the 1950s and 1960s. For the time series bounded to 2006. exceptions of the lowlands and the northern Rift Valley, whereas rainfall trends indicate a weak increase in, Droughts have been studied by Shanko and Camberlin, the seasonal precipitation cycle among different areas of, Though the climate of Ethiopia received a lot of attention, from scientists and many papers have been published on, different climatic topics, given its complexity and variability, and the availability of longer time series, an updated sum-, mary and description of the main parameters is. Precipitation here is about 1058 mm | 41.7 inch per year. Ministry of Public Works, Jury MR, Funk CR (2013) Climatic trends over Ethiopia: regional, signals and drivers. for time series and trend analysis, especially for rainfall. The empirical analysis also confirmed that the basin losses a total of about 89.6 Mt of soil annually. All zones experienced drought at the annual scale, although in most zones, previous droughts were more extreme. ), which is con-, ) measured a mean annual temperature of 34.7, C were commonly recorded in the Samoti plai, ). 17 . The climate is warm and temperate in Lemmi. In the Rift Valley (e.g., Awasa, Ziway), these conditions are paired by a particularly. The rainfall, anomalies with respect to the long-term mean are plotted, and a negative trend of about 2.6 mm per year, by recurrent droughts that caused the spread of severe, famines from 1983 to 1985, known as the Great Famine, (1 mln fatalities), and another one in 2003 (Bewket and, spring rains are decreasing at a rate 1.5 times faster than the, monsoon summer rains. enced by local orographic or morphologic factors. The mean maximum. Ethiopia provides a good example of the influence of climate variability on a developing country’s economy. Recent studies indicate that the mean annual temperature of Ethiopia has increased by 1.3 °C between 1960 and 2006, at an average rate of 0.28 °C per decade and by 0.3°C per decade in the south-west and Amhara in the north, ... Dangila town and its surrounding areas have a mean annual rainfall of 1640 mm, as measured (since 1988) at the National Meteorology Agency (NMA) weather station at Dangila, 91% of which falls from May to October (Walker et al., 2019a). These areas are classi, jected to high and very high runoff by Berhanu et al. http://clearinghouse5.fgdc.gov/enraemed/NMSA. bela, a maximum difference of +175 mm is observed. Ethiopia is located in the Horn of Africa.It is bordered by Eritrea to the north, Djibouti and Somalia to the east, Sudan and South Sudan to the west, and Kenya to the south. At 1,000 m, the mean values are close to 30. mainly, in the steppe areas and the Danakil Desert (Fig. This study suggests the need for an integrated assessment and enhancement of adaptive capacity with all its components rather than focusing only on asset possession as an indicator of adaptive capacity. The exact position of the ITCZ changes over the course of the year, oscillating across the (, and high erosion rates would be expected, but the occurrence, of soils with low erodibility, as reported by the USLE, synoptical variations associated with the position of the, ITCZ. conditions results in ample thermal differences (Fig. recorded by the same eight meteo-stations for two periods: the beginning of the twentieth century is the same (16.4, much larger daily excursion, i.e., 15.2 versus 13.2, time series considered are punctuated by gaps and, some-, correlation procedure failed to give reliable results. The findings of this study are not only relevant for a better understanding of the WAM, but also provide insights into the role of multiphase rotational extension during rifting and passive margin formation in general. Precipitation: 3.75" Humidity: 59%. Drought-related disasters could be mitigated by warnings if skillful summer rainfall predictions were possible with sufficient lead time. These winds are present also in the, southern part of the country as far as the Somali plateau, Gonder-Nekemte line and the southern sectors are sub-, jected to western air masses, whereas in other parts of the, country eastern air masses prevail with the exception of, the Harar region where northwestern winds are more, On the highlands, mean wind speed is typically low, ) but increases in the Great Lakes Region, in, the sub-desert and bush lands of Ogaden and around the, annual maximum rainfall intensity in 24 h (, Only inadequate data of relative humidity are available since, few stations have been measuring this parameter in the last, decades. minimum temperatures are for the same points and girds, but cover the period 1981–2011. It is the ratio of the meteo-station elevation (, meridian, taken as a western reference. Many other records, started during the 1980s, following the impulse from the, Ethiopian Government to expand the network, partly in, response to the mid-1980s drought. sists mainly of alpine prairie and arboreal species is absent. In this study, the trend and variability of rainfall were compared with the perception of farmers in northern Ethiopia. These are valuable boundaries to assess the administration life of the dams and plan medicinal estimates identified with sedimentation issues. local physiography nor by the expansion of the urban areas. 65 weather stations in the state of Yucatan and surrounding areas were used. The study attempts to identify global and more regional processes affecting the large-scale summer climate patterns that govern rainfall anomalies. 9. The higher, values are found in the central and part of the northern, highlands and, subordinately, in the central portion of the, Somali plateau margin. The remaining area were ranging from low to high erosion risk class. This rain gauge is located in, triangle at an elevation of 423 m s.l.m., but the driest, Asab, in Eritrea, with only 45 mm.
