A composition on a typhoon day
Writing in typhoon days sometimes pays more attention to skills. You can't write well without hard work and painstaking efforts. A single standard will kill students' enthusiasm for writing, and compositions without real materials are boring. Learn skills from composition in typhoon days! Let's have a look!
Composition on Typhoon Day 1 It was sunny the afternoon before yesterday. Suddenly, the sky darkened, and the dark clouds in the sky surged like the tide of the sea. Immediately, a strong wind blew. In an instant, sand and stones are flying and loess is flying. The wind is getting closer and closer, and gray clouds float up from all directions, blocking the last bright sky.
It turned out that the typhoon was coming, and I was on pins and needles after learning the news. I am afraid of typhoons because there was a typhoon in my primary school. At that time, we were still in class, and I saw a bang. Lightning struck a pole outside the classroom. Just bang, the light flashed and the pole exploded. At that time, the math teacher was still teaching with multimedia. Later, a thin flash of lightning struck the multimedia, and the teacher was startled. In class, chickens fly and dogs jump, and screams overflow. This left me with the shadow of a typhoon. At night, the wind is more wanton. It is like a huge devil, blowing wantonly in the air. At this moment, I heard the wind whistling, as if calling for a wolf. Accompanied by the subtle sound of raindrops. I went to the window and saw the branches and leaves of the tree swaying from side to side by the wind. Under the light, the shadows of the branches kept turning, as if telling their sufferings. A big tree nearby, its branches and leaves are swaying in the wind, rustling and making a crisp sound. The dead branches and leaves on the tree are separated from the mother instantly, just like a boat without rudder, paddle and sail, where it is blown by ruthless wind.
Suddenly, as soon as lightning broke through the sky, thunder roared and woke me up in my sleep. In a blink of an eye, it rained cats and dogs from the sky, and raindrops as big as peas hit the roof tiles and the ground, just as Malik was rushing; Under the sudden wind and rain, the air is full of danger and anxiety, which makes me afraid to pray all the time.
I think I didn't do anything wrong on weekdays, afraid it was a typhoon. Besides, no one else is afraid, and I have no reason to be afraid! Thinking about thinking about it, my courage gradually increased. Finally, courage triumphed over fear. I finally overcame my fear of typhoon. The next morning, although the power of the typhoon weakened a lot, it was inevitable that there were waves of "rumbling" from time to time, which woke me up in my sleep. Then I remembered some grass trees in the corner of the yard, so I got up and put on my clothes and came to the balcony. I saw: after the storm, it stood unscathed, shaking its head, and after the baptism of rain, the vitality of that cause was pouring out. Even the grass is not afraid of this typhoon, how can I be afraid! Although the typhoon is terrible, the courage in my heart is the weapon to defeat it.
In the classroom, the students were listening attentively when suddenly there was a muffled sound-"pa". Rain eagerly broke free from the embrace of the sky and fled to the world, like getting on one bullet train after another and leaving it behind. "Cough-"A heavy cough drew our eyes back to the classroom.
"cheep-"the broadcast rang: "students, according to the notice from the superior, there will be heavy rain on the avenue in the next few hours and a strong typhoon tomorrow. Please pay attention to safety on the way back and forth, and the notice is over. " Go home from school and wait for the typhoon.
July 18 Weather: cloudy
As soon as I entered the classroom, I saw my classmates studying hard. Suddenly a classmate rushed into the classroom to "broadcast the news": "Do you know? I heard from a class teacher that there is no typhoon today, but there will be tomorrow. It is said that it is very likely to have a holiday! "
"really! ? "A classmate looks suspicious.
That classmate patted his chest: "It's true. I do things, don't worry! "
"oh! Holiday! "
"Holiday!"
A burst of exclamation attracted the teacher in the next class: "What sound! I want to take the exam and not review it. " Everyone belongs.
It was windy on June 19.
I shook my hair messed up by the typhoon and walked into the classroom. In class, the teacher still lets us study by ourselves. A bold classmate asked, "Teacher, shall we have a holiday?"
"Don't let go." The teacher answered with a straight face.
"But there is a typhoon." This classmate still won't give up. The teacher pushed the reading glasses and glanced at the class. "The typhoon can't blow you away, I am with you." Bend your head and correct your unfinished homework.
All fifty lights went out.
Weather on June 20th: cloudy.
"alas! The typhoon has come and gone. "
"It seems that someone loathe to give up the typhoon. I'll call it. " The fellow villager held a pencil case close to his ear: "Hello, is this Brother Typhoon?" ? Someone here is begging you, come back quickly! "
When that guy finished, the whole class became silent.
Our mood is like a field hit by a typhoon.
In fact, everyone knows that the senior high school entrance examination is coming, and we need to study hard, but there is always a voice in my heart shouting, "We are just a group of children, let's have our own time." But no, since it is inevitable, then face it and strive for the senior high school entrance examination. Say "Come on!" Give it to yourself.
Typhoon Day Essay 3 Both typhoons and hurricanes are strong tropical cyclones generated on the surface of tropical oceans, but they appear in different places and have different names. Tropical cyclones that occur in the western part of the North Pacific Ocean and west of the international international date line, including the South China Sea, are called typhoons; Tropical cyclones in the Atlantic Ocean or the eastern North Pacific Ocean are called hurricanes, which means hurricanes in the United States and typhoons in the Philippines, China, Japan and East Asia. It is called a whirlwind in the southern hemisphere. The cause of typhoon is that tropical sea surface is directly exposed to sunlight, which makes the temperature of seawater rise, and the seawater evaporates into steam to take off, while the surrounding cold air flows in to replenish it, and then rises again. This cycle will eventually expand the whole airflow and form a "wind".
The horizontal distribution of various meteorological elements and weather phenomena in typhoon can be divided into three areas: outer cloud area (including outer cloud area and inner cloud area), cloud wall area and typhoon eye area. The vertical direction can be divided into three levels: low-altitude inflow layer (below 1 km), high-altitude outflow layer (above 10 km) and middle-level updraft layer (from 1 km to 10 km). In the lower layer around the typhoon, several spiral air currents with isobars in the typhoon area are involved in the typhoon area and converge to rise, which promotes the convective cloud system. There are several spiral rain belts in the corresponding cloud system. The more spiral airflow involved in a typhoon, the faster the tangential wind speed becomes. At a certain distance from the typhoon center, the airflow no longer hovers, so a lot of wet air is forced to rise strongly, forming a towering cloud wall around the center. The top of the cumulonimbus cloud wall can be as high as 19 km, which is the cloud wall area.
At the lower level, typhoons mainly flow into low-pressure inflow. Because of the angular momentum balance, the inner region can produce strong wind speed, and the outflow airflow of anticyclone is in the upper layer. Strong upward movement connects the upper and lower circulation, which is the main feature of typhoon circulation.
In a typhoon, the wind speed occurs inside the cloud wall, and the rainstorm occurs in the cloud wall area, so the cloud wall area is the storm area most prone to disasters. In 2006/KOOC-0/Strong typhoon "Canzhu" caused a total of/KOOC-0/04 deaths and lost/KOOC-0/200 million US dollars. In 2006, the No.4 tropical storm "Billis" caused 672 deaths and 4.4 billion US dollars in losses in the Philippines, Taiwan Province Province and southeastern China. In 2005, the super typhoon "Wang Long" (19) caused heavy storms in Taiwan Province, Fujian, Guangdong and Jiangxi provinces, and caused some casualties. It can be seen that the cloud wall area is destructive.
Therefore, strengthening the monitoring and forecasting of typhoons is an important measure to reduce typhoon disasters. Meteorological satellites are mainly used to detect typhoons. The existence and size of the typhoon can be clearly seen on the satellite cloud picture. Using meteorological satellite data, we can determine the location of typhoon center, estimate the intensity of typhoon, monitor the direction and speed of typhoon movement, and the area where severe storms occur, which plays a key role in preventing and mitigating typhoon disasters. When the typhoon reaches the offshore, the radar can also detect it. Establish the city's early warning system, improve emergency response capabilities, and establish an emergency response mechanism. There are also forecasters of meteorological stations, who, based on all kinds of information obtained, analyze the trend of typhoons, the place and time of landing, issue typhoon forecasts, typhoon emergency reports or emergency warnings in time, serve the public through television, radio and other media, and provide decision-making basis for governments at all levels. Issuing typhoon forecast or emergency report is an important measure to reduce typhoon disaster.
