Forbidden City Beijing: Teleconnection Analysis Using Lamb Weather Types - Essay Sample

Introduction

The analysis is done in the Forbidden City Beijing to determine the teleconnection and the synoptic analysis through the use of the lamb weather types to accurately determine the geographical scale and the geological classification of Beijing. The Forbidden City, mostly known as the Palace Museum or the Old Palace, is located in the downtown of Beijing, the capital of China. The City is located in the North-East of the country bordering the South China Sea. The coordinates of Forbidden City are 9 54 '54.70 "North / 116 23' 25.71" East. Forbidden City is a hot and wet region having the right amount of annual rainfall and good regulated amount of sunlight over a year (Zhan et al., 2019). The City bordering the China Sea allows for better agriculture as one of the main economic activities taking place in the region (Mathbout et al., 2019).

Teleconnection and Synoptic Pattern Used

This report intends to discover the synoptic and the teleconnection patterns in the Chinese City. The teleconnection pattern refers to the recurring large scale pattern of pressure circulation anomalies spinning in a big geographical area (Feldstein & Franzke, 2017). Teleconnection helps in the adequate understanding of the weather and the possible effects that may come about by the weather changes. Synoptic patterns refer to the view together of the different parameters of the earth's atmosphere (Wu et al., 2016). The synoptic pattern is used to analyze the atmospheric phenomenon of a region that is on a smaller scale compared to the previous one. The Lamb weather type can be used for the classification of the synoptic circulation based on the single grid point sea level pressure analysis. The lamb weather type is classified into ten categories, including the eight directional categories and the two velocity categories.

Analysis

Teleconnection Patterns in the Forbidden City

In atmospheric science, teleconnection patterns refer to the climatic anomalies of a place related to other sites on different points of the map (Wu et al., 2016). In other words, teleconnection is the atmospheric changes of a given location and how it affects the weather conditions of different sites miles away. Forbidden City lies in central Beijing of the Northern part of China, something that makes it be in a strategic location supported by the neighboring China Sea that plays significant roles in affecting its weather patterns and other areas as well (Wu et al., 2016). The City also lies in the metropolis area about 70 miles (102km) west of the Bohai Sea. It also borders Hebei province to the north and other potential physical features that fundamentally affects the weather patterns and changes in the region. Topographically, Forbidden City in Beijing lies on flat low land with an altitude elevation of about 40-60 meters above sea level. The highest point of central Beijing is approximately 88 meters above sea level and overlooks the Forbidden City.

Lamb Weather Type Analysis of Forbidden City Teleconnection Patterns

The lamb weather type of analysis, recognizes significant changes in weather-type frequency that addresses the "anticyclonic, cyclonic, easterly, northerly, westerly, southerly, and northwesterly aspects (Cortesi et al., 2016)." Due to the hot air from the northern Siberian region and the humid air pressure from the Bohai Sea, summer experiences severe smog problems, something that also affects other areas of southern and eastern parts of China. The mountains that guard the City against the Gobi steppes equally form some semi-circular basin that creates massive environmental air pollution not only to the City but to its neighboring areas as well. The monsoon winds from the southern parts of the City also prevent potential pollutants from leaving the basin, something that makes the Forbidden City experience environmental challenges. During winter, the wind currents reverse their course as the anticyclone high pressure brings cold, dry air from the Siberia. During the spring season, the weather conditions in central Beijing adversely affect the western parts of China by causing desertification and dust storms as a result of the northerly winds.

Regarding hydrology, the Forbidden City is also surrounded by rivers such as Chaobai, Juma, and Yongding that flow through the Beijing municipality. All the rivers originate from the Shanxi and Hebei mountains in the northern side of the City and flow through the western and north mountains of the City. The destination of these rivers is the Bohai Sea, and hydrologists have successfully utilized these rivers to make human-made lakes and moats to restore the water supply in the City. It is imperative to note that the Forbidden City is strategically surrounded by several physical such as the mountains, rivers, and Seas, something that the agriculturalists have utilized to strengthen agricultural production and agribusiness. The human-made lakes and channels have been used to create irrigation schemes that produce more than 70% of non-staple food in the entire Beijing. This has led to significant springing levels of agro-tourism, high-tech agro-enterprises, and enterprise-based food processing industries in Beijing and the whole country.

Synoptic Weather Patterns of Forbidden City

Synoptic weather map refers to the geographical indicators in the map used to understand how weather patterns change within a given place (Zhan et al., 2019). Given the Forbidden City's geographical location that borders the China Sea, several atmospheric patterns come to play to inform its weather, climate, and other essential atmospheric patterns. In the Global Positioning System (GPS), the coordinates of the Forbidden City Beijing lie at Latitude 39.9163447 and longitude 116.3971546 in the grid system (Wei et al., 2017). Due to the City's grid location, it experiences a long, humid, and warm summer, while the winters are dry, clear, and mostly freezing. Annually, the City experiences varying temperatures between 17 and 88 degrees F, but rarely goes below ten and never goes above 96 as well.

The cold and dry air that comes from the Siberian region fundamentally affects the daily atmospheric weather changes in the Forbidden City and other parts of Beijing (Zhan et al., 2019). It is a collection of the dry and cold air that comes from the north that only causes no or rare rainfall during winters. During November, the City experiences the most extended period of rains than any other month in the year, but the rain capacity only ranges about 3.5mm. Due to the latitude and longitude grid location, the Forbidden City experiences spring between April and May every year. During this period, the temperatures vary sharply between day and night. The general climate is windy, warm, and dry, with sandstorms occurring mainly at night.

The city experiences summer between June and August, which comes with abundant rainfall and scorching temperature. During summer, the temperature of the City rises to between 30 to 40 degrees Celsius. The City also experiences sporadic short rainstorms that always come in the afternoons on sunny days during summer. Forbidden City experiences long winters that start from November to March every season. During winters, the average temperature in the City and its environs may fall to zero degrees Celsius. During December, January, and February, the western hills form snow and mist most parts of the day. During Autumn (September to October), the City experiences mild temperatures and plenty of sunshine, and the fragrant hills give a flaming maple scene. Generally, the synoptic weather patterns of the Forbidden City of Beijing can be summed as having long hot summer, short windy spring, long chilly winter, and pleasant cold autumn. It is equally imperative to note that its geographical location in the grid map plays an integral role in informing its warm and windy climate throughout every season.

Conclusion

In literature, the climatic patterns can get clarified by teleconnection designs and concise examples. Notwithstanding, right now Forbidden City, it appears that the job of teleconnection is less significant than the brief one taking into account the blended relationships between the Forbidden's climatic information and West Pacific Index in the relapse work out. Teleconnection examples may relate better for more significant considering scale like an area or nation as opposed to a solitary city which is a little point in the enormous picture and may go amiss from the area or nation regular pattern. The use of concise and teleconnection investigation helps understanding varieties of the meteorological parameters in Tianjin over a massive geological scale. The Lamb investigation offices understandings how the overall breezes influence precipitation and temperature regularly. Because of the fluctuating conviction in relapse results, the planetary-scale teleconnection example will be unable to distinguish a profoundly exact climatic investigation for the single city Tianjin. Be that as it may, it pretty much shows conceivable irregularity in Tianjin's climatic conditions.
