Phoenix effect

One is that the climate "Phoenix" effect is fading, and the temperature in Shencheng will slowly rise in the coming week.

No matter how strong the "Phoenix" is, there will always be a weak day. After two or three days of strong winds and showers, our city will gradually move away from the "Phoenix" effect from 3 1. On the afternoon of the 30th, the news from the Municipal Meteorological Bureau said that there will still be southerly winds and showers and precipitation in 3 1 Japan, but the intensity will be significantly worse than the previous two days. Since August 1 day, the wind and rain in this city have weakened, and the temperature will slowly rise to around 35℃ in the coming week.

The peripheral cloud system of "Phoenix" not only brought trouble to Shencheng, but also brought coolness. According to meteorological data, from 8: 00 to 30: 00 on the 29th, the biggest rainfall in this city is Songjiang 62.7mm, followed by Jiading 44.7mm, Jinshan 4 1.3mm, and other areas are generally between 17.4-32.6mm ... However, due to a large number of clouds in the sky, strong winds blow away the heat in the air, outside the city of Fenghuang. As of 2 pm on the 30th, the highest temperature in the city was 30.6℃.

This year's No.8 tropical storm "Phoenix" entered the northeast of Jiangxi Province through the northwest of Fujian the night before yesterday. At 8: 00 am on the 30th, the center was located near Poyang Lake in Jiangxi Province, about 5 10 km southwest of our city, and the maximum wind force near the center was still 9. After that, Fenghuang continued to move to the north-north direction at a speed of about 15 km per hour.

In this regard, meteorologists said that from the actual situation, the moving path of "Phoenix" is obviously westward compared with that of "Seagull", but because the main body of "Phoenix" is strong and wide, the intensity decreases slowly after landing, and the main wind and rain areas are located in its east and south, while the scope of "Seagull" is small, and the intensity decreases rapidly after landing, so the impact of "Phoenix" on the wind and rain in this city is more obvious and lasts longer.

There is also an extension based on the butterfly effect.

A butterfly flapping its wings occasionally in the tropical rain forest of the Amazon River basin may trigger a tornado in Texas in two weeks.

Butterflies and Tornadoes In the early 1960s, meteorologist EdwardLorenz (a professor at the Massachusetts Institute of Technology and one of the founders of chaos) made an experiment of "numerical weather forecast" by computer. He found that as long as there are small differences in the input data, the calculation results will be very different. "Small differences are thousands of miles away" is only used to describe this situation. This shows that "numerical weather forecast" is also unpredictable to some extent.

Based on this discovery and extensive research, Lorenz 1972 12 published a book entitled "Predictability: Will a butterfly dancing in Brazil cause a tornado in Texas?" The main idea of the speech is: a butterfly in the tropical rain forest of the Amazon River basin occasionally flaps its wings a few times, and two weeks later it may cause a tornado in Texas, USA. The reason is that the movement of butterfly wings leads to the change of the air system around it, resulting in a weak airflow, which in turn will cause the corresponding changes of the surrounding air or other systems, causing a chain reaction, and finally leading to a huge change in the weather system.

Lorenz's speech and conclusion left a deep impression on people. Since then, the so-called "butterfly effect" has spread like wildfire and gained popularity. Butterfly effect shows that the result of the development of things is extremely sensitive to the initial conditions, and the smallest deviation of the initial conditions will cause great differences in the results.

With the economic recovery, some bad stocks suddenly turned into phoenix. . Phoenix effect.
