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. A rise in average temperature of about 1.3Â°C has been observed between 1960 and 2006. Equinox appears twice a year. Details such as the sort of bodies of water are in or near the area, as well as the area’s location upon the earth, are important factors in determining what sort of climate is in that specific region of the world. The Dega zone usually is a zone where crops such as barley3, wheat4, and pulses5are grown. (1500 â 2400 m.a.s.l) to wurch zone at the upper elevations (above 3700 m.a.s.l). There, frost is a frequent phenomenon, and afro- alpine grasslands2are the dominant land use type if altitudes are not too high even for these perennial or annual grasses. MitigationÂ measuresÂ areÂ thoseÂ actionsÂ thatÂ areÂ takenÂ toÂ reduceÂ andÂ controlÂ greenhouseÂ gas emissions changingÂ theÂ climate.Â Moreover,Â itÂ impliesÂ reducingÂ theÂ flowÂ ofÂ heatÂ trapping greenhouse gases into the atmosphere, either by reducing sources of these gases or enhancing the âsinksâ that accumulate and store these gases(such as the oceans, forests and soil).The goal of mitigations is to avoid significant human interference with the climate system. Increase the use of renewable energy such as solar. Continental climates have very cold winters and hot summers with an average annual precipitation between 24 and 48 inches. Throughout history, people and societies have adjusted to and coped with changes in climate and extremes with varying degrees of success. Yearly temperature in dry-hot climates is usually above 64 degrees Fahrenheit. Climate. The Weynadega zone also hosts crops such as wheat, barely, fava bean and chickpea. Indigenous tree species. Adaptation is simply defined as adapting to life in a changing climate. 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. Southern part of Ethiopia receives highest records of temperature in autumn and spring following the relative shift of the sun; whereas in the northern part of the country, summer season is characterized by higher temperature. Although meanÂ annualÂ rainfallÂ isÂ erratic,Â itÂ canÂ beÂ asÂ highÂ asÂ 1500Â mmÂ inÂ theÂ wetÂ westernÂ lowlands Â of Gambella. No significant variation in length of day and night between summer and winter. Physical characteristics, such as oceans, affect the moisture in the air, ultimately affecting the climate of the region. Kolla (lowlands, 500 -1,500, sorghum, finger millet, sesame, cowpeas, groundnuts) 3. Wildlife 10. A continental climate, otherwise known as a micro-thermal climate, can be found in the Northern Hemisphere near the east and north-western coasts. The exact number of zones is unclear, as the names and number of zones given in documents by Ethiopia's Central Statistical Agency differ between 2005 and 2007. It appears to happen when the visible sun moves south across the celestial equator on 23rd of September. The study aims to assess trends in extremes of surface temperature and precipitation through the application of the World Meteorological Organizationâs (WMO) Expert Team on Climate Change Detection and Indices (ETCCDI) on datasets representing three agroecological zones in Southern Ethiopia. A continental moderate climate is another sub-type of temperate climates. Djibouti,Â majorityÂ ofÂ Somalia,Â andÂ coastalÂ areasÂ ofÂ EritreaÂ areÂ categorizedÂ under Kolla and Bereha zones. The warm to hot, semi-arid zone includes those areas with an altitude of 500â1,500 m, average annual rainfall generally of around 600 mm (but as high as 1,600 mm in the western lowlands of Gambella), and an average annual temperature range of 20â28°C; The warm to cool, semi-humid zone covers the temperate highlands between 1,500 and 2,500. The characteristics for semi-arid zone as described in UNESCO (1979) were adopted. Hence, the zone includes most of the agricultural land. The topographic feature of the administration is range from 927 DESERT. Altitude is the main factor that determines the spatial distribution of temperature in Ethiopia. Both hemispheres during this event has either the most or least sunlight of the year. Ethiopia is in the tropical zone laying between the Equator and the Tropic of Cancer. High-dega and temperate climate zones are found in between the two. In other words, though Ethiopia is found within the tropic, is not a hot country since its altitudinal climate 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. Vernal (spring) equinox marks the beginning of Spring season.Â March 21 marks the offset of the vernal equinox. Lots of plants that do well in zone 7b will do well in zone 9b too, especially if the type is noted as being heat/drought tolerant. Over the last decades, Ethiopia has experienced climatic changes. The temporal variability of rainfall is characterized by; Based on rainfall distribution, both in space and time, four rainfall regions can be identified in Ethiopia and the Horn. The impact of climate change is higher in low income countries, since they have limited capacity to cope with the changes. The normal yearly precipitation over the entire nation of Ethiopia is 817 mm year â1 (Fazzini et al. Temperate climates, otherwise known as meso-thermal climates, are cooler than subtropical climates, but warmer than polar climates. The ITCZ shifts towards south of equator (Tropic of Capricorn) in January. Climate Zones of World Map; View Political World Map with countries boundaries of all independent nations as well as some dependent territories. The summer remains dry in steppe dry climates. The indices are applied to daily temperature and precipitation data. They are limited to the lowlands in the peripheries. The distribution of weather and climate elements over the surface of the earth is uneven in terms of magnitude and time.Â Hotness or coldness, rainy or cloudiness, sunniness, windiness or calmness, of air you are feeling on the daily base in your current location are expressions of weather. The warming of earth planet in the past 50 years is majorly driven by human activities. The five main latitude regions of Earth's surface comprise geographical zones, divided by the major circles of latitude.The differences between them relate to climate.They are as follows: The North Frigid Zone, between the North Pole at 90° N and the Arctic Circle at 66° 33' N, covers 4.12% of Earth's surface. In Ethiopia, the geographic peripheries in south, southeast, west and northeastern part are mainly in this category. World's continents, historical maps, world spoken languages, physical map and satellite images. The central European climate zone is a product of maritime and continental air masses. There are some mitigation measures that can be taken to avoid the increase of pollutant emissions. Weynadega is relatively cooler and wetter than Kolla with annual rainfall from below 900 mm up to over 1,400 mm. The climate is different in all the countries in the world. The regions of Ethiopia are administratively divided into 68 or more zones (Amharic: áá, zonÉ). These include latitude, altitude/elevation, revolution of the earth and inclination of the earthâs axis, nearby water/ distance from water bodies, ocean currents, topography/ mountain barriers, vegetation, and prevailing winds.Â Moreover, the global climate system and any changes that occur within it also influence local climate. The different kinds of polar climates include tundra climates and ice cap climates. Spatiotemporal Patterns and Distribution of Temperature and Rainfall in Ethiopia5.4 Agro-ecological Zones of Ethiopia5.5. Daily maximum temperature varies from a high of more than 370c over the lowlands in northeast and southeast to a low of about 10 -150c over the northwestern and southwestern highlands. In general, the weather that impacts the surface of the Earth and those that live on the surface takes place in the troposphere. HumanÂ inducedÂ greenhouseÂ gasesÂ suchÂ asÂ carbonÂ dioxide,Â methaneÂ andÂ nitrousÂ oxideÂ have caused much of the observed increase in Earth’s temperatures over the past 50 years. The Bale Mountains are among highlands where lowest mean annual temperatures are recorded. This is a hot zone with annual average temperature of 20-28°C (68-82°F) and annual rainfall of about 500 millimetres. BesidesÂ spatialÂ andÂ temporalÂ variationsÂ inÂ differentÂ partsÂ ofÂ theÂ country,Â EthiopianÂ climate experiences extremes such as drought, flood etc. Higher rise in temperature was noted in drier areas in northeast and southeast part of the country. Andosols dominate in the wurch zone while Regosols dominate in the dega zone (Figure 3). The very hot and moist conditions cause a lot of convection rainfall. Both weather and climate are composed of the following elements: temperature, air pressure, humidity, wind, sunshine, precipitation etc. Kolla is the climate of the hot lowlands with an altitudinal range of 500 to 1500 meters above sea level. It refers to any change in climate over time, due to either natural variability or human activities. Details such as the sort of bodies of water are in or near the area, as well as the areaâs location upon the earth, are important factors in determining what sort of climate is in that specific region of the world. High-dega and temperate climate zones are found in between the two (Falch and Keiner, 2000). However, deserts are categorized according to the amount of rainfall, rather than by landforms, and can be hot or cool/cold. 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. and Rogosols (24%) cover the large portion of the study area. Average temperatures are up to 32°C and annual rainfall can reach 2000 mm. With groupings from the Koppen climate classification system 12 Climate Zones Climate Zones of the World By: Aidan Richardson Thank you for your time! Ethiopia as a large country in the Horn of Africa is characterized by a wide variety of altitudinal ranges and diverse climatic conditions. The decompositionÂ ofÂ wastesÂ inÂ landfills,Â agriculture,Â ruminantÂ digestionÂ andÂ manure management,Â syntheticÂ compoundsÂ manufacturing, clearingÂ ofÂ landÂ forÂ agriculture,Â industrial activities,Â andÂ otherÂ humanÂ activitiesÂ haveÂ increasedÂ concentrationsÂ ofÂ greenhouseÂ gases.Â The major gases that contribute to the greenhouse effect include Water vapor, Carbon dioxide (CO2), Methane,Â NitrousÂ oxide,Â ChlorofluorocarbonsÂ (CFCs).Although,Â methaneÂ isÂ lessÂ abundantÂ in atmosphere, it is by far more active greenhouse gas than carbon dioxide. The first of these â Dega â refers to coldish, less than temperate zones with altitudes ranging between 2,600 and 3,200m. 5.1 the role of altitude in modifying tempreture. Ethiopiaâs daily temperatures are more extreme than its annual averages. Climate is the state of the atmosphere over long time periods, decades and more.Â It is the composite of daily weather conditions recorded for long periods of time. The seasonal and annual rainfall variations are results of the macro-scale pressure systems and monsoon flows which are related to the changes in the pressure systems. TheÂ industrialÂ activitiesÂ thatÂ ourÂ modernÂ civilizationÂ dependsÂ uponÂ haveÂ raisedÂ atmospheric carbon dioxide levels from 280 parts per million to 400 parts per million in the last 150 years.
