Biome (Desert)- Climate Affecting Soil And
With reference to one biome that you have studied, account for the type of climate experienced in this biome and explain how this climate impacts on soils and vegetation within the biome. (80 marks) Marking Scheme: Number of aspects discussed: 3 @ 20 marks each 4 @ 15 marks each For each aspect: Identifying aspect 4 marks 3 marks Discussion 8 x SRPs 6 x SRPs Overall Coherence 20 marks graded* 20 marks graded* In this answer, I choose 3 aspects to discuss (1. Climate, 2. Climate’s impact on soil and, 3. Climate’s impact on vegetation). Overall coherence means how well your answer is structured (Introduction, main section, conclusion – well-structured and coherent) and do you keep to the point/ answer the question directly. Introduction: In this answer I am going to discuss the type of climate experienced in the hot desert biome and how this climate impacts on soils and vegetation within this biome. Biomes are classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment. They are a large geographical area controlled by climate. Therefore the climate of a particular region will affect what type of soil is formed in that biome as well as what types of plants (flora) grow there. The hot desert that I have studied is the North American Desert Biome. Body of Topic: A desert biome can be defined as an arid region that is characterised by little or no rainfall, in which vegetation is scarce or absent, unless it has specially adapted. As a result of its location, between 15º and 30º north of the Equator, the climate of the hot desert biome is hot and dry. -

Synoptic-Scale Control Over Modern Rainfall and Flood Patterns in the Levant Drylands with Implications for Past Climates
JUNE 2018 ARMONETAL. 1077 Synoptic-Scale Control over Modern Rainfall and Flood Patterns in the Levant Drylands with Implications for Past Climates MOSHE ARMON Fredy and Nadine Herrmann Institute of Earth Sciences, Hebrew University of Jerusalem, Givat Ram, Jerusalem, Israel ELAD DENTE Fredy and Nadine Herrmann Institute of Earth Sciences, Hebrew University of Jerusalem, Givat Ram, and Geological Survey of Israel, Jerusalem, Israel JAMES A. SMITH Department of Civil and Environmental Engineering, Princeton University, Princeton, New Jersey YEHOUDA ENZEL AND EFRAT MORIN Fredy and Nadine Herrmann Institute of Earth Sciences, Hebrew University of Jerusalem, Givat Ram, Jerusalem, Israel (Manuscript received 23 January 2018, in final form 1 May 2018) ABSTRACT Rainfall in the Levant drylands is scarce but can potentially generate high-magnitude flash floods. Rainstorms are caused by distinct synoptic-scale circulation patterns: Mediterranean cyclone (MC), active Red Sea trough (ARST), and subtropical jet stream (STJ) disturbances, also termed tropical plumes (TPs). The unique spatiotemporal char- acteristics of rainstorms and floods for each circulation pattern were identified. Meteorological reanalyses, quantitative precipitation estimates from weather radars, hydrological data, and indicators of geomorphic changes from remote sensing imagery were used to characterize the chain of hydrometeorological processes leading to distinct flood patterns in the region. Significant differences in the hydrometeorology of these three flood-producing synoptic systems were identified: MC storms draw moisture from the Mediterranean and generate moderate rainfall in the northern part of the region. ARST and TP storms transfer large amounts of moisture from the south, which is converted to rainfall in the hyperarid southernmost parts of the Levant. -
The High Desert Alfalfa Production Region of California Is Located From
ALFALFA PRODUCTION IN THE HIGH DESERT Steve B. Orloff and Rhonda R. Gildersleeve' ( The high desert alfalfa production region of California is located from the Mojave Desert which includes portions of Los Angeles, San Bernardino, and Kern Counties, north to Inyo and Mono Counties. Alfalfa fields in the high desertare clustered in isolated valleys with long stretchesof desert betweenthem. Thesevalleys are so isolated and dispersedthat the climate, growing conditions, soil types, and even the production practices and problems can vary considerably between production areas. The main alfalfa production areas and their characteristics are presentedin table 1. Many people mistakenly believe that "desert" is "desert", and lump the high desert with the low desert. However, those that are familiar with both areas realize there are very distinct differences. The climate in the high desert is unique, but has similarities with both the low desert and the colder northern parts of the state. The high desert climate is characterized by large swings in temperature, both from day to night and from summer to winter. Winter low temperatures between zero to ten degrees(negative 10 to 20 in the northern mountain valleys) have been recorded (particularly this last year), while summer temperatures exceeding 110 degrees commonly occur. A drop in temperature of 40 to 50 degreesbetween day and night is not uncommon. Spring frosts as late as April (and even June in northern high-elevation areas) are routine, and slow alfalfa growth. Winds are a common denominator throughout all of the high-desert valleys. Most areas have a prevailing "breeze" of 10 to 20 miles per hour during the day. -
North American Deserts Chihuahuan - Great Basin Desert - Sonoran – Mojave
North American Deserts Chihuahuan - Great Basin Desert - Sonoran – Mojave http://www.desertusa.com/desert.html In most modern classifications, the deserts of the United States and northern Mexico are grouped into four distinct categories. These distinctions are made on the basis of floristic composition and distribution -- the species of plants growing in a particular desert region. Plant communities, in turn, are determined by the geologic history of a region, the soil and mineral conditions, the elevation and the patterns of precipitation. Three of these deserts -- the Chihuahuan, the Sonoran and the Mojave -- are called "hot deserts," because of their high temperatures during the long summer and because the evolutionary affinities of their plant life are largely with the subtropical plant communities to the south. The Great Basin Desert is called a "cold desert" because it is generally cooler and its dominant plant life is not subtropical in origin. Chihuahuan Desert: A small area of southeastern New Mexico and extreme western Texas, extending south into a vast area of Mexico. Great Basin Desert: The northern three-quarters of Nevada, western and southern Utah, to the southern third of Idaho and the southeastern corner of Oregon. According to some, it also includes small portions of western Colorado and southwestern Wyoming. Bordered on the south by the Mojave and Sonoran Deserts. Mojave Desert: A portion of southern Nevada, extreme southwestern Utah and of eastern California, north of the Sonoran Desert. Sonoran Desert: A relatively small region of extreme south-central California and most of the southern half of Arizona, east to almost the New Mexico line. -

Keys Ranch: Where Time Stood Still
National Park Service Teaching with Historic Places U.S. Department of the Interior Keys Ranch: Where Time Stood Still Keys Ranch: Where Time Stood Still (Photo by Harmon and Nelda King, National Park Service) In the high desert of California, flesh-colored boulders rise up out of the stark landscape and embrace a small valley where Keys Ranch stands. Strangely shaped trees cast long shadows on the sides of the simple wooden ranch structures. Animal tracks in the sand tell of the previous night's adventures when scorpions, kangaroo rats, snakes, and bobcats battled for survival. This seemingly hostile desert environment was settled much later than other more productive areas of the West. Yet it was here, in 1917, that Bill Keys chose to establish a ranch and raise a family. Keys and other 20th-century homesteaders lived much as earlier pioneers in the West had, working hard to make their marginal land holdings successful. Today, Keys Ranch is preserved as part of Joshua Tree National Park.
