Ask the geography teacher about manhattanhenge.

You should know that manhattanhenge is a special phenomenon, and not all of it will appear in the southern hemisphere.

the word "manhattanhenge" was first used by Neil de manhattanhenge Tai Sen, an astrophysicist at the American Museum of Natural History, in 22. It is applied to those grid streets that conform to the Commissioners' Plan of 1811 in new york. These streets conform to the law of deviation of 28.9 degrees from east to west. Because these streets are just on the east-west line, the time when the landscape appears coincides with the vernal equinox and autumnal equinox, forming a harmonious combination of nature and artificial buildings.

When the sun sets behind the Chrysler Building with three-dimensional decorative art in new york, the whole building shows a golden luster.

Long before European immigrants set foot on Manhattan Island, it was covered with lush forests and mixed with some shrub pastures, just like other areas in the northeastern United States. Early immigrants built the town at the mouth of the river at the southern end of the island for navigation and military reasons. With the development of economy, in order to cope with the pressure of urban expansion, especially in order to facilitate the sale of land, the New York State Assembly adopted a planning proposal put forward by a three-member Committee in 1811, and divided the undeveloped areas of Manhattan Island in a checkerboard pattern. In this plan, the vertical and horizontal streets are perpendicular to each other. One of the directions is basically parallel to the west coast of the island along the direction of the island, which is usually called "north-south direction", while the direction perpendicular to it is called "east-west direction". Therefore, there is actually an included angle of 28.9 degrees between the east-west street on Manhattan Island and the actual east-west direction, or latitude direction, which is biased towards the southeast-northwest direction.

for various reasons, this plan has not been faithfully implemented. Compared with today's Manhattan map, the most obvious difference is that the rectangular area between Fifth Avenue and Eighth Avenue and between 59th Street and 11th Street has not been developed, thus becoming today's "lung of new york"-Central Park. In addition, there is a "Broadway" that runs obliquely through the north and south of the island, which also destroys the checkerboard street layout. New york's oldest subway line 1 runs through the whole island almost along the underground of this street. Perhaps, you may be more familiar with its other famous translation name-Broadway. The so-called "Broadway" in new york's song and dance dramas refers to the section of this street between 42nd Street and 5th Street, and a part of its west. Schematic diagram In this urban environment of Manhattan, it is almost impossible for the sun to spread all over the street. As a result, on special days, the sunshine across the island along the street has become a "wonder", which is really rare for New Yorkers. In fact, in a year, except December 5, the sunrise on January 8 is also parallel to the east-west street. The midpoint of the above two days in time happens to be the winter solstice. On May 28th and July 12th, the afterglow of the sunset will run through the east-west streets of Manhattan. The midpoint of these two days happens to be the summer solstice. Maybe when you plan to travel to new york again, you can choose these four days or the dates around them to experience this not mysterious but spectacular sight for yourself.
