लॉस एंजेल्स अमरीका के कैलिफोर्निया प्रांत का सबसे बडा शहर एवं पूरे देश का दूसरा सबसे बडा शहर है।[1] शहर को अक्सर बोलचाल में एल ए, कहा जाता है एवं इसकी अनुमानित जनसंख्या ३.८मिलियन[2] एवं क्षेत्रफल ४६९.१ वर्गमील (१,२१४.९ वर्ग किमी) है। यदि इसमें ग्रेटर लॉस एंजेल्स की आबादी शामिल की जाए तो इसकी आबादी लगभग १२.९ मिलियन[3] हो जाती है जिनमें पूरी दुनिया से आए लोग शामिल हैं एवं २२४ अलग-अलग भाषाएं बोलते हैं। लॉस एंजेल्स शहर लॉस एंजेल्स काउंटी क प्रशासनिक मुख्यालय भी है एवं जो अमरीका में अत्यंत सघन बसा हुआ एवं काफी विविधता वाला काउंटी है।[4] इस काउंटी में रहने वालों को "एंजीलियंस" कहकर संबोधित किया जाता है।
लॉस एंजेल्स की स्थापना १७८१ में स्पैनिश गवर्नर फेलिपे दे नेवे द्वारा की गयी थी। स्पेन से आजाद होने के बाद यह शहर १८२१ में मेक्सिको का हिस्सा बना एवं १८४८ में मेक्सिकन अमरीकी युद्ध के समाप्त होने के बाद, अमरीका एवं मेक्सिको के बीच हुई एक संधि के तहत अमरीका द्वारा खरीद लिया गया। १८५० में कैलिफोर्निया के पूर्ण राज्य घोषित होने से पांच महीने पूर्व ४ अप्रैल को इसे नगर निगम का दर्जा भी हासिल हुआ। आज लॉस एंजेल्स पूरी दुनिया के संस्कृति, तकनीक, मीडिया, व्यापार के क्षेत्र में एक प्रमुख शहर के रूप में स्थापित है।
इतिहास लॉस एंजेल्स तटीय क्षेत्र सबसे पहले हजारो वर्ष पूर्व तोंगवा एवं चुमाश (मूल अमरीकियों की प्रजातियां) लोगों से आबाद हुआ था। यहां पहुंचने वाला पहला यूरोपीय १५४२ में आनेवाला पुर्तगाली खोजी नाविक ह्वान रोड्रिग्स कैबरिलो, था जिसने इसे स्पेन साम्राज्य के लिए देवताओं का शहर घोषित किया।; हलाकि उसने यहां कोई बस्ती नहीं बसाई।[5] उसके बाद यहां का बाहरी दुनिया से संपर्क दूसरी बार २२७ साल बाद तब हुआ जब गैस्पर दि पोर्ताला, एवं ह्वान क्रेस्पी नाम के फ्रांस के दो इसाई मिशनरी २ अगस्त १७६९ को यहां पहुंचे। क्रेस्पी को ही पहले पहल इस क्षेत्र को बसाने की बात सूझी।[6]
भूगोल टोपोग्राफी लास एंजेल्स की स्थालाकृति काफी विषम है, इसका कुल क्षेत्रफल लगभग ४९८.३ वर्गमील (१,२९०.६ किमी²), जिसमे ४६९.१ वर्गमील (१,२१४.९ किमी²) स्थल एवं २९.२ वर्गमील (७५.७ किमी²) जलीय हिस्सा है। इस लिहाज से क्षेत्रफल के अनुसार यह संयुक्त राज्य अमरीका का चौदहवां सबसे बडा शहर है।[7] The city extends for 44 miles (71km) longitudinally and for 29 miles (47km) latitudinally. The perimeter of the city is 342 miles (550km). It is the only major city in the United States bisected by a mountain range.
The highest point in Los Angeles is Mount Lukens, also called Sister Elsie Peak. Located at the far reaches of the northeastern San Fernando Valley, it reaches a height of 5,080ft (1,548 m). The major river is the Los Angeles River, which begins in the Canoga Park district of the city and is largely seasonal. The river is lined in concrete for almost its entire length as it flows through the city into nearby Vernon on its way to the Pacific Ocean.
भूगर्भ Los Angeles is subject to earthquakes due to its location in the Pacific Ring of Fire. The geologic instability produces numerous fault lines both above and below ground, which altogether cause approximately 10,000 earthquakes every year.[8] One of the major fault lines is the San Andreas Fault. Located at the boundary between the Pacific Plate and the North American Plate, it is predicted to be the source of Southern California's next big earthquake.[9] Major earthquakes to have hit the Los Angeles area include the 1994 Northridge earthquake, the 1987 Whittier Narrows earthquake, the 1971 San Fernando earthquake near Sylmar, and the 1933 Long Beach earthquake. Nevertheless, all but a few quakes are of low intensity and are not felt.[8] Parts of the city are also vulnerable to Pacific Ocean tsunamis; harbor areas were damaged by waves from the Valdivia earthquake in 1960.[10]
जलवायु The city is situated in a Mediterranean climate or Dry-Summer Subtropical zone (Köppen climate classification Csb on the coast, Csa inland), USDA Zones 8-11, experiencing mild, somewhat wet winters and warm to hot summers. The prevalent warm southerly airflow and the blocking effect of mountains to the north give the city a much warmer climate than would be expected. The average annual temperature is 18.86°C (around 66°F)[11], much higher than comparable coastal locations at the same distance from the equator elsewhere such as Sydney or Cape Town. Breezes from the Pacific Ocean tend to keep the beach communities of the Los Angeles area cooler in summer and warmer in winter than those further inland; summer temperatures can sometimes be as much as 18°F (10°C) warmer in the inland communities compared to that of the coastal communities. A few coastal "micro-climates" have never recorded a temperature below freezing. Coastal areas also see a phenomenon known as the "marine layer," a dense cloud cover caused by the proximity of the ocean that helps keep the temperatures cooler throughout the year. When the marine layer becomes more common and pervades farther inland during the months of May and June, it is called May Gray or June Gloom.[12]

Temperatures in the summer can exceed 90°F (32°C), but average summer daytime highs in downtown are 82°F (27°C), with overnight lows of 63°F (17°C). Winter daytime high temperatures reach around 65°F (18°C), on average, with overnight lows of 48°F (10°C) and during this season rain is common. The warmest month is August, followed by July and then September. This somewhat large case of seasonal lag is caused by the influence of the ocean and its latitude of 34° north.
The median temperature in January is 57°F (13°C) and 73°F (22°C) in August. The highest temperature recorded within city borders was 119.0°F (48.33°C) in Woodland Hills on July 22, 2006;[13] the lowest temperature recorded was 18.0°F (−7.8°C) in 1989, in Canoga Park. The highest temperature recorded for Downtown Los Angeles was 112.0°F (44.4°C) on June 26 1990, and the lowest temperature recorded was 28.0°F (−2.0°C) on January 4 1949.[14]
Rain occurs mainly in the winter and spring months (February being the wettest month), with great annual variations in storm severity. Los Angeles averages 15 inches (385mm) of precipitation per year. Tornado warnings are also issued, which are extraordinarily rare downtown, though waterspouts are seen during severe storms at beaches. Snow is extraordinarily rare in the city basin, but the mountainous slopes within city limits typically receive snow every year. The greatest snowfall recorded in downtown Los Angeles was 2.0inches (5cm) on January 15, 1932.[15]
वनस्पति The Los Angeles area is rich in native plant species due in part to a diversity in habitats, including beaches, wetlands, and mountains. The most prevalent botanical environment is coastal sage scrub, which covers the hillsides in combustible chaparral. Native plants include: California poppy, matilija poppy, toyon, Coast Live Oak, and giant wild rye grass. Many of these native species, such as the Los Angeles sunflower, have become so rare as to be considered endangered. Though they are not native to the area, the official tree of Los Angeles is the tropical Coral Tree and the official flower of Los Angeles is the Bird of Paradise, Strelitzia reginae.[17]
पारिस्थितिक मुद्दे Owing to geography, heavy reliance on automobiles, and the Los Angeles/Long Beach port complex, Los Angeles suffers from air pollution in the form of smog. The Los Angeles Basin and the San Fernando Valley are susceptible to atmospheric inversion, which holds in the exhausts from road vehicles, airplanes, locomotives, shipping, manufacturing, and other sources.[18] Unlike other large cities that rely on rain to clear smog, Los Angeles gets only 15inches (381mm) of rain each year. Pollution accumulates over multiple consecutive days. Issues of air quality in Los Angeles and other major cities led to the passage of early national environmental legislation, including the Clean Air Act. More recently, the state of California has led the nation in working to limit pollution by mandating low emissions vehicles.[19]
As a result, pollution levels have dropped in recent decades. The number of Stage 1 smog alerts has declined from over 100 per year in the 1970s to almost zero in the new millennium. Despite improvement, the 2006 annual report of the American Lung Association ranks the city as the most polluted in the country with short-term particle pollution and year-round particle pollution.[20][21] In addition, the groundwater is increasingly threatened by MTBE from gas stations and perchlorate from rocket fuel. With pollution still a significant problem, the city continues to take aggressive steps to improve air and water conditions.[22][23]
