This current is known as Peru coastal current near the coast and Peru oceanic current off the coast. Mean yearly temperature extends in the vicinity of 14°C and 17°C and the normal speed of moving water is 15 nautical miles (27km) every day. The temperature of sea water increases from the coast towards the ocean. Occasionally a set directly toward land is encountered. At about Cabo Blanco, where the coast falls away to the right, the current curves toward the left, past the Galapagos Islands, where it takes a westerly set and constitutes the significant segment of the South Equatorial Current, along these lines finishing the counterclockwise circulation of the South Pacific.
Hurricane Grace was drifted upwards by its cold front into a warm zone of circulation of the deep cyclone on Oct 29th. The cyclone strikingly got stronger as a result of a temperature contrast between the cold air to the northwest and the warmth and humidity from the remains of hurricane Grace. As the low pressure system proceeded to get deeper, hurricane Grace changed to a secondary contributor to the extraordinary sea conditions. It had a strange reverse motion for a nor’easter. The centre of the extratropical low strayed southeastward and then south westward,
The polar cell is the smallest and weakest cells among the three. It extends from between 60 and 70 degrees north and south of the poles. In these cells air sinks over the highest latitudes and flows out towards the lower latitudes at the surface. High precipitation in the tropics is caused by the warm air from the hemispheres converging in the Inter Convergence Zone(ICZ) and the rise of this air is caused by low pressure and causes convection in the atmosphere. In the tropics, high precipitation occurs as a result of warm prevailing winds being obstructed by mountain ranges, since the mountains force the moisture in those winds to sink on the side of the mountain that is blocking the winds, leaving the other side with low
The Khitans themselves eventually submit to the Jurchen people, who founded the Jin Dynasty. The Jin dynasty favored the Balhae people as well as the Khitans. Jurchen proclamations emphasized the common descent of the Balhae and Jurchen people from the seven tribes, and proclaimed "Jurchen and Balhae are from the same family". The fourth, fifth and seventh emperors of Jin were mothered by Balhae consorts. The 13th century census of Northern China by the Mongols distinguished Balhae from other ethnic groups such as Goryeo, Khitan and Jurchen.
Article Summary of Running Wild Submitted by Jonathan Garcia El Centro College GEOL 1401, Section 51428, Fall 2014 Article Summary of Running Wild London based freelance writer Stephen Battersby explains the threat of extreme weather in his 2012 article titled Running Wild. The title is an apparent play on words attempting to convey the manner in which our climate is changing. In his opening paragraphs Battersby describes the freak occurrence “summer in March” in which a ten day event in the northern hemisphere caused much warmer than usual temperatures. As an example, the author uses a town in Michigan called Pellston that experienced a one day temperature record that surpassed the previous high by more than seventeen degrees.
1. An El Nino is an event where warmer waters are pushed to the region of Central America, caused by a shift in the atmospheric pressures that typically occur near the equator. Typically, the winds blow across the Pacific Ocean from East to west, moving from a high to a low-pressure system. These so called “trade winds” have an a effect on the water current that pushes the surface of the oceans to the west, thus creating an upwelling of cold water by Central America (Ahrens, 2014). In an El Nino scenario, the trade winds that typically push west in a strong manner cannot compensate for a strong shift in pressure.
Introduction The Hakkas are Han Chinese people with origins related to Hakka-speaking provincial areas of Guangdong, Fujian, Jiangxi, Guangxi, Sichuan, Hunan, Zhejiang, Hainan and Guizhou. The Hakkas originated from the lands bordering the Yellow River (today, the Chinese provinces of Shanxi, Henan, and Hubei). During the years of the Northern Song dynasty and the following Southern Song dynasty (1127-1279), the attacks by Jin people forced many people to move to the south. They mostly moved to Tingzhou, an area in southwest Fujian, forming the Hakka group. The Hakka people achieved some notable advances, particularly in developing cultural activities to enrich their communal life.
Kublai Khan, born Kublai and also known by the temple name Shizu, was the grandson of Genghis Khan. He was born on September 5th ,1215 in Mongolia and died on the 18th of February 1294 in Khanbaliq. He was the fifth Khan of the Mongol Empire, reigning from 1260 to 1294, and conquered China, and became the founder of the Yuan dynasty in Mongolia and China, a division of the Mongol Empire. To govern China as always going to be a challenge as it had such a long political history. In this paragraph you will become aware of five of Kublai Khan’s achievements.
In these essay, we will point on the two-main cause and two-main negative effect of the hurricane and some idea of the basic preparation. One of the reason that cause hurricane it’s depend on environment. Hurricane use the warm air and warm ocean as the power of the storm. As being said, the warm temperature that form above the ocean create the rotating wind because when warm air and cool air are touching together then it makes an area of lower pressure, warm air is lighter than cool air so higher air pressure pushes into the lower pressure area and it cause hurricane. Second reason that cause hurricane is the global warming, you might didn 't know that the climate change can lead to the storm and another natural disaster.
Titov and Synolakis (1995) and Titiov and Gonzalez (1997) describes the MOST (the short form of Method of Splitting Tsunami) model, a model developed at the Pacific Marine Environmental Laboratory (PMEL) of National Oceanic and Atmospheric Administration (NOAA) in Seattle, USA. The model simulates all the three stages of tsunami. The elastic deformation theory of Gusiakov (1978) and Okada (1985) was used for the initial tsunami generation. Murty (1984) reported that the earth's curvature is also taken into account. The tsunami propagates large transoceanic distances and hence the momentum and continuity equations are written in spherical polar co-ordinates.
