Rain of blood and weather phenomena of 'bad crying and laughing' in history

Rain 'blood', snow falling between the desert or fire cannons . are extreme weather conditions that once threatened human life.

Over the past days, Saigon people constantly experience the winter feeling of the North. Specifically, the outdoor temperature is at its lowest level in the last 8 years because the cold air makes most people wear warm clothes and masks when going out.

This strange weather phenomenon makes many young people feel excited. However, many people are concerned that this is a sign of climate change that is getting worse.

Not only in Saigon but in the world, we have also witnessed a lot of similar strange weather phenomena.

'Blood' rain is one of the weather phenomena recorded early in history from ancient Rome. This phenomenon occurs when strong winds blow red sand from the desert to the atmosphere. Then, the red sand makes the rain fall in a strange color and the ancient inhabitants call it 'blood' rain . They have the same nature as fish rain, frog rain . that many people still know.

The most recorded 'blood' rain occurs in Europe when storms and strong winds bring sand from the Sahara desert here.

The 'jump' temperature refers to a sudden change in weather conditions. World history has seen many times this phenomenon occurs when the outdoor temperature increases and decreases by a dozen degrees Celsius within minutes.

Typically, on January 22, 1943, people in Spearfish, South Dakota experienced the feeling of changing 27 degrees Celsius for 2 minutes (from -20 degrees C to 7 degrees C).

By 1966, residents of Pincher Creek, Alberta also experienced a similar situation when in 4 minutes, the outdoor temperature increased by 21 degrees Celsius. Both places are in North America and heavily influenced by the wind .

Due to the impacts of climate change, the phenomenon of super- hot weather takes place with increasing frequency and severity. In Marble Bar, Australia, from October 31, 1923 to April 7, 1924, people had to be friends with the hot Sun for 160 consecutive days. It is estimated that the average temperature during that period reached more than 37.8 degrees C.

Most recently in 2003, a record heat wave also "swept" across Europe (especially France) and caused nearly 70,000 deaths from shock and heat stroke.

Besides the terrible heat waves, it is impossible not to mention the super winters when the temperature drops at a record. Consecutively in 2013 and 2014, due to the impact of the polar cyclone, the United States suffered from this phenomenon.

America's temperature at that time fell to -50 degrees Celsius. Most recently, the United States was almost paralyzed when drowning in snowfall as high as 2 meters in December 2014.

Snow falling in the desert is also an extremely strange phenomenon that happened. On average every 7 years, snow falls on the top of Tibesti in the Sahara desert. In particular, in February 1979, low-altitude areas in the Sahara also witnessed unusual snow showers.

Since then, the same phenomenon has repeated quite a lot. Typically, the sudden snowfall between summer in the desert of Acatama, Chile in 2011 or the first snowfall in Egypt after about a century in 2013.

If you go to the Catalumbo river in Venezuela, you have the opportunity to witness the phenomenon of lightning continuity. When the hot and humid air from the Catalumbo River evaporates and encounters the cold air above, great lightning strikes will be spectacular.

Adding methane concentration (CH ₄ ) here is quite high, which increases the electrical conductivity of the clouds. Consequences of lightning appeared a lot at once, forming a continuous lightning.

Fire cannons are rare when there is a combination of vortex and outdoor temperatures high or contain flammable gases. Compared to regular water hoses, the power of this phenomenon is much more frightening.

In 1923, a fire cannon killed 38,000 Japanese in Tokyo within a mere 15 minutes. In 2003, another fire dragon was noted to cause a massive forest disaster in Canberra. This dragon nozzle has a diameter of nearly 500m, moving at a speed of 250km / h and the center temperature can reach more than 1,000 ^o C.

With the increasing seriousness of climate change, extreme weather events will take place more and more complex. Don't wait, join hands to protect the Earth and fight climate change from the smallest actions!
