Common sense of storm safety

Jellyfish belong to invertebrates. At present, there are more than 200 species of jellyfish found in the world, including jellyfish and jellyfish.

Jellyfish is divided into two parts: umbrella part and mouth and wrist part. "Umbrella" is a flat disc or hemisphere with numerous short and thin tentacles and sensory balls on the edge. There is a mouth in the abdomen of the "umbrella", and the wrist hangs under the mouth and floats in the water.

The lower part of the umbrella is called the mouth and wrist, and there are many tentacles on it. Normally, jellyfish always float on the sea surface, and their distribution is dominated by wind direction, wind force, ocean current and tidal current.

Sometimes they gather together and stretch for miles; Sometimes the gathered jellyfish will drift away overnight. Jellyfish float on the upper layer or surface of the water in calm, clear water, cloudy or weak sunshine and low tide.

Whenever there is a big storm, rainstorm, turbid water, low tide or too strong sunshine, it will generally sink to a lower level or near the bottom. Strangely, whenever a storm warning comes, jellyfish can predict and react quickly.

So, why do jellyfish predict the arrival of storms? Scientists have found that before the "Ocean Symphony" aroused by crazy, roaring winds and roaring waves, there is an infrasound wave (8? 13 Hz), faster than the wind and waves. This infrasound can't be felt by humans, but jellyfish can feel it. Later, scientists made in-depth research, and it turned out that there was a small auditory stone in the ball beside the "umbrella" of jellyfish, which seemed to be the "ear" of jellyfish.

Infrasound waves generated by the friction between waves and air hit the auditory stone and * * * touched the surrounding nerve receptors, enabling jellyfish to capture the sound of the storm more than 10 hours ago. As a result, they seem to have accepted the order and immediately sank into the depths of the ocean to avoid being crushed by the huge waves aroused by the storm.

Inspired by the ability of jellyfish to predict storms, people simulated their sensors and successfully made a storm predictor, which can receive infrasound waves from the sea 15 hours in advance and predict the direction and time of storm warning at sea.

2. How to learn from mental storms?

Mission profile 1.

Talk to Dorothy (72, 137) on the 93rd floor of Sheraton Tower, and select Yes to get the rusty key. 2。

Open the rusty treasure chest and collect props at the coordinates below the 93rd floor of Sherawesen Tower. (54。

98) → Introduction to Synthesis (168). 1 1 1)→ "night grass" (1 14.

54) → Ricardo Roberto Barreto da Rocha's Teeth (1 18. 154)→ "face tree" The above items disappear when leaving the snow tower or logging off.

3。 Come back and talk to Dorothy (72, 137), choose "Yes", hand over the collected props, and generate branches according to different occupations.

Branch 1: mage, missionary, wizard, sorcerer, casting sword, doctor, seal, dancer, animal trainer (all occupations that can be equipped with walking sticks), talk with barris on the 92nd floor of Sherawesen Tower, and gain skills: mental storm, which costs 6000G, and enters the 92nd floor of Sherawesen Tower to transmit stones (68. 109) returns to the 93rd floor.

Branch 2: Soldiers, thieves, ninjas or people who have learned skills will get the "Angel Light Ring" and send it back to the 93rd floor. Angel light ring: grade 1, headdress, slash -3~0, hit +6, durability 200.

================================== 。 .

Copy it.

It is suggested that level 70 is safer, so don't go alone.

Do your best.

3. How to pay attention to safety

1. Try to stay indoors and don't go out easily; Outdoor pedestrians should return to the house as soon as possible, because flying objects outside can easily hurt people.

2. Unplug the power plug and TV antenna in thunderstorm weather. If the wire breaks and falls, power supply is interrupted, etc. , should notify the relevant departments for maintenance, must not touch by hand, in order to prevent electric shock.

3. If the roof is blown away, the indoor wires are short-circuited and caught fire, and the doors and windows are scraped off, the first thing to do is to cut off the power and put out the fire in time, and then deal with other problems; If it's not easy to solve at the moment, move to another house as soon as possible. 4. When floods, mountain collapses, waves and other phenomena endanger the safety of houses, we must resolutely move to a safe place.

5. Listen to the weather forecast broadcast at any time, master the dynamic changes of tropical storms, and arrange preventive measures accordingly.

4. Who is the storm chaser?

Storm chasers refer to scientists and amateur storm lovers who track and intercept major storms and tornadoes.

They chase storms for two reasons: first, to collect data for studying major storms; Second, it provides visual observation for the severe storms marked by radar stations. In addition, TV workers who track storms can provide video information about the rapid changes of storms.

Chasing the storm is a very dangerous activity, because the strong wind, heavy rain, hail and lightning produced in the process will threaten people's lives. Storm chasers need behavior training for severe storms.

Roger? Zhan Sen (1933-2001) is considered as the first active storm chaser. As a "self-taught" weather observer and professional photographer, he spent 50 years recording data of tornadoes and thunderstorms.

David? David Hoadley (1938-) is regarded as a pioneer in this field. He was the first person to report current events with the theme of "Storm Trail". The first scientist to become a storm chaser was Neil? Neil Ward (1914-1972) once worked in the National Severe Storm Laboratory in Norman, Oklahoma, and was officially named "the father of storm chasing" because of his rich qualifications.
