wurch zone of climate

These include latitude, altitude/elevation, revolution of the earth and inclination of the earth’s axis, nearby water/ distance from water bodies, ocean currents, topography/ mountain barriers, vegetation, and prevailing winds.  Moreover, the global climate system and any changes that occur within it also influence local climate. Its  average  annual  rainfall  is  less  than  200  mm, and average  annual  temperature  is  over  27.5oc.  Strong  wind,  high  temperature,  low  relative humidity,  and  little  cloud  cover  usually  characterize  Bereha.  Evapotranspiration is always in excess of rainfall. In dry-cold climates, the temperature is usually below 64 degrees Fahrenheit. The variation in the amount of solar radiation received daily is small throughout the year. For example, three Ethiopian cities, Bako, Addis Ababa, and Awash all lies on the 90 N latitude, and therefore they might be expected to receive equal magnitudes of direct rays from the sun and therefor equal temperature. Higher rise in temperature was noted in drier areas in northeast and southeast part of the country. The warming of earth planet in the past 50 years is majorly driven by human activities. Liana Thomas began writing professionally in 2008. As the earth revolves around the sun, this inclination produces a change in the directness of the sun’s rays; which in turn causes the directness of the sun and differences in length of day cause seasons. They are limited to the lowlands in the peripheries. Nonparametric Sen’s slope estimator and Mann–Kendall’s trend tests are used to detect the magnitude and statistical significance of changes in … High-dega and temperate climate zones are found in between the two. We understand your requirement and provide quality works. 2015). According to the ICH guidelines for stability studies, the climate of the world is divided into five different zones. A plant's performance is governed by many climate related factors including the length of the growing season, the amount of rainfall, winter lows, summer highs, wind or humidity. The regions have fresh summers and wet winters with mild weather. The regions of Ethiopia are administratively divided into 68 or more zones (Amharic: ዞን, zonə). The Weynadega zone also hosts crops such as wheat, barely, fava bean and chickpea. Over the last decades, Ethiopia has experienced climatic changes. These regions have hot, rainy summers and cold, dry winters. The Autumn equinox: appears to happen when the sun crosses equator giving approximately equal length between day and night. Due to the various different types of foods found within rainforests, many different species of animals are also found within tropical climates. The second zone – Weyna Dega – … Average annual temperature ranges between 20oc and 30oc. Ethiopia ranked 5thout of 184 countries in terms of its risk of drought. When we speak of the latitudinal impact on the climate of Ethiopia and the Horn, we are considering the intensity of temperature in the region. It has three different climate zones according to elevation. Unfortunately I don't know if there's an equivalent map for Canada to figure out which zone you'd be in, but since I live very close to the border, I use the part of the map closest to my area. It has to be noted that certain seasons should have special considerations. The climate of Ethiopia is mainly controlled by the seasonal migration of the Inter-Tropical Convergence Zone (ITCZ) and associated atmospheric circulation, but the topography has also an effect on local climate conditions. In many parts of the world, climate change has already caused loss of life, damaging property and affecting livelihoods. APPENDIX 5 LAND USE AND LAND COVER EXPLANATION This map was compiled from the following main sources imagery interpretation of The Wurch-zone is an area having altitude higher than 3,200 meters above sea level and mean annual temperature of less than 10 0 C. Mountains having typically fitting characteristics of this zone include mountain systems of RasDashen in SemineGonder, Guna in South Gonder, Megezez in North Shoa, Batu in Bale, Choke, AbuneYoseph, etc. In other words, though Ethiopia is found within the tropic, is not a hot country since its altitudinal climate Climate Zones of World Map; View Political World Map with countries boundaries of all independent nations as well as some dependent territories. using statistical tests) by changes in the mean and/or the variability of its properties and that persists for an extended period, typically decades or longer. west africa. Revolution of the Earth and Inclination of the Earth's Axis, 5.3.1. weather and climate. In the tropics, the daily range of temperature is higher and the annual range is small, whereas the reverse is true in the temperate latitudes. The impact of climate change is higher in low income countries, since they have limited capacity to cope with the changes. The moderate oceanic climate is a sub-type of temperate climates. Moreover, revolution of the earth along its orbit, the inclination of its axis from the plane of that orbit, and the constant position(parallelism) of the axis causes seasonal changes in the daylight and darkness periods. This area consists of the Danakil Depression (about 125 metres below sea level and with average temperature of about 34°C or about 93°F), the valleys of … Tall trees and many different kinds of plants are found in tropical regions. Latitude is the distance of a location from the equator. Improve water storage and use is some of measures taken by cities and towns. It is the astronomical first day of summer in the Northern Hemisphere.  The sun is at its highest position in the noonday sky, directly above 23 ½ in the Tropic of Cancer. Indigenous tree species. The severe drought of 2015-2016 was exacerbated by the strongest El Nino that caused successive harvest failures and widespread livestock deaths in some regions. In the country, 12 extreme drought events were recorded between 1900 and 2010.  Among  the  12,  seven  of  the  drought  events  occurred  since  1980.  The majority of these resulted in famines. The tropical climate zone stretches from the Tropic of Cancer at 23.5 degrees north latitude to the Tropic of Capricorn at 23.5 degrees south latitude, with the equator centered within this zone. In Ethiopia, this variation in climate is traditionally divided into three main climatic zones: Dega, Weyna Dega and Kolla. Increase the use of renewable energy such as solar. This paper reviews impact of climate change on Ethiopian agriculture. High daily and small annual ranges of temperature. This is because the temperature and the amount of energy reaching the surface is directly related with the directness of the sun.The direction of rain bearing winds (leeward or windward side) also determines the temperature variations in mountainous regions. The Sun is high in the sky for the whole year. Agriculture is the main sector of Ethiopian economy that contributes 50% of GDP. Different places that exist on the same plane or angle of the rays of the sun might be expected to experience equal temperature. The Dega and Wurch zones’ cultivation is highly dominated by barley, which covers about 57 and 78 per cent of the land cultivated, respectively. Dega and Wurch are wetter and colder than the remaining zones often These are: As a result of the diversified altitude and climatic conditions, Ethiopia possesses diversagroclimatic zones. The indices are applied to daily temperature and precipitation data. A continental moderate climate is another sub-type of temperate climates. A walk through of climate zone descriptions of weather, vegetation, and characteristics. The goal is to reduce our vulnerability to the harmful effects of climate change such as extreme weather events or food insecurity.  It  also  encompasses  making  the  most  of  any  potential  beneficial  opportunities associated with climate change (for example, longer growing seasons or increased yields in some regions). In Ethiopia, as in all places in the tropics, the air is frost free and changes in solar angles are small making intense solar radiation. Kolla (lowlands, 500 -1,500, sorghum, finger millet, sesame, cowpeas, groundnuts) 3. Spatiotemporal Distribution of Rainfall, 5.5.1. Some of the consequences of the changing climate include: How do our forefathers react to the changing climate?  Do we have any traditional (indigenous) mechanism? The shift takes place when the trade winds from the north retreat giving the space forequatorial westerlies. Climate change refers to a change in the state of the climate that can be identified (e.g. The different kinds of polar climates include tundra climates and ice cap climates. Climate within the tropical zone varies from the tropical wet regions of the rain forest, to the drier arid and semi-arid climate of north Africa or central Australia. Following the directness of the Sun in March and September around the equatorthe ITCZ shifts towards equator. The climate is different in all the countries in the world. However, their altitudes very, and therefore their temperatures vary, as shown in table 5.1. The highest mean maximum temperature in the country is recorded in the Afar Depression.Moreover, lowlands of north-western, western and south-eastern Ethiopian experiences mean maximum temperatures of more than 300C.Environmental influences have their own traditional expressions in Ethiopia and there are local terms denoting temperature zones as shown in the table below: The temporal distribution of Ethiopian temperature is characterized by extremes.The major controls determining its distributions are latitude and cloud cover. Deserts are often found in dry climates and they remain dry during the winter seasons. and Rogosols (24%) cover the large portion of the study area. The coldest temperatures in the world are found in Antarctica, which is an ice cap climate. Spatiotemporal Distribution of Temperature, 5.3.2. This system divides the nation into five major climatic zones namely Bereha, Kolla, WoinaDega, Degaand Wurch. This zone has warmer temperature and moderate rainfall.  It lies between 1500-2,300 meters above sea level.  It is the second largest zone covering more than 26% of the landmass of Ethiopia. lower altitude (1500 – 2400 meters above sea level) to wurch zone at the upper elevations ( 3700 meters above sea level). Traditional zone: 1. In some regions, total average rainfall is showing decline. Latitude, humidity and winds, with varying magnitude have also significant impacts on temperature conditions in Ethiopia. The WeynaDega zone has also two growing seasons. Weynadega is relatively cooler and wetter than Kolla with annual rainfall from below 900 mm up to over 1,400 mm. Ethiopia is in the tropical zone laying between the Equator and the Tropic of Cancer. However, due to the impact of altitude, they do not. This is a zone of highlands having relatively higher temperature and lower altitude compared to the wurch Zones. Physical characteristics of continental climates include forests and prairies with tall grasses. Tropical rainforests are found in tropical climates. I wrote above that temperature is the parameter, but that's not a full description, of course. Besides  spatial  and  temporal  variations  in  different  parts  of  the  country,  Ethiopian  climate experiences extremes such as drought, flood etc. The region is boundary between the hot arid (Bereha) and the humid climates (WoinaDega).
