Latest Weather: Thunderstorms

Hi there! I decided to do thunderstorms for my weekly research and I thought that this time of year would be perfect. I’d like to thank my mother Camilla for making this possible.

A thunderstorm is a storm with lightning and thunder. It is produced by a cumulonimbus cloud, usually producing gusty winds, heavy rain and sometimes hail but not always in the Western USA. The basic ingredients used to make a thunderstorm are moisture, unstable air and lift.

The earth needs moisture to form clouds and rain. You need unstable air that is relatively warm and can rise rapidly. Finally, you need lift.

The lift can form from fronts, sea breezes or mountains. Thunderstorms can occur year-round and at all hours. But they are most likely to happen in the spring and summer months and during the afternoon and evening hours.

Some people estimated that there are around 1,800 thunderstorms that occur across our planet every day. All thunderstorms are dangerous. Every thunderstorm produces lightning, which kills more people each year than tornadoes.

Thunder is the sound caused by lightning. The intense heat from lightning causes the surrounding air to rapidly expand and create a sonic wave that you hear as thunder. The average temperature of lightning is around 20000°C (36000°F).

The sound of thunder can be anything from a loud crack to a low rumble. Light travels faster than sound so we see lightning before we hear thunder. The closer you live, the shorter the gap between the lightning and thunder.

The speed of sound is around 767 miles per hour (1,230 kilometres per hour). The speed of light is around 669600000 miles per hour (1080000000 kilometres per hour). Thunder is difficult to hear at distances over 12 miles (20 kilometres).

Thousands of years ago, philosophers such as Aristotle believed that thunder was caused by the collision of clouds. Astraphobia is the fear of thunder and lightning. The Oklahoma basketball team that play in the National Basketball Association (NBA) are called the Thunder.

Nature: Research for Carnations

Subscribe to Lillian Darnell by Email

Hi there! Camilla has let me pick my own assignment. I chose a flower. I would have done more flowers but Camilla said to choose only one flower. So I chose carnation.

The single flowers of the Carnations species, Dianthus caryophyllus (that’s the scientific name) has 5 petals and they can vary from white to pink to purple in colors. Border Carnation cultivars may have double flowers with 1 to 40 petals. When they grow in gardens, Carnations grow to between 6 and 8.5 cm in diameter. Petals on Carnations are generally clawed or serrated.

Carnations are bisexual flowers and bloom simply or in a branched or forked cluster. The stamens on Carnations can occur in one or two whorls, in equal number or twice the number of the petals. The Carnation leaves are narrow and stalk less and their color varies from green to grey-blue or purple. Carnations grow big, full blooms on strong, straight stems. The carnation’s history dates back to ancient Greek and Roman times, when it was used in art and decor.

Christians or some spirituals believe that the first carnation bloomed on earth when Mary wept for Jesus as he carried his cross. Carnations in these early times were predominantly found in shades of pale pink and peach, but over the years the palette of available colors has grown to include red, yellow, white, purple, and even green. Throughout so many centuries of change, the popularity of the carnation has remained undiminished. The fact that the carnation continues to endure is a testament to its vast appeal.

The meanings of carnations include fascination, distinction, and love. Like many other flowers, different messages can also be expressed with the flower’s different color varieties. Light red carnations, for example, are often used to convey admiration, whereas the dark red version expresses deeper sentiments of love and affection. White carnations are associated with purity and luck, and pink carnations are often given as a sign of gratitude.

In the early part of the 20th century, carnations became the official flower of Mother’s Day in addition finding particular significance in many other cultures worldwide. To this day, carnations remain a favorite flower choice for many different occasions. They are immediately recognizable flowers, and they possess a charm and allure that continues to captivate people around the globe. In fact, in many parts of the world, the popularity of carnations surpasses that of any other flower including roses.

The powerful sentiments these flowers can express are a perfect complement to their classic beauty and long-lasting freshness. Carnation is a flowering plant that belongs to the family Caryophyllaceae. There are over 300 varieties of carnations that can be found throughout the world. These plants originate from Europe and Asia.

Carnations are cultivated at least 2000 years because of their beautiful flowers and intense fragrance. Carnations require well drained soil, enough moisture and direct sunlight for successful growth. These flowers are symbol of labor movement and mother’s love in the most countries of the world. Some people in France believe that carnations symbolize bad luck, where they are used mostly for the preparation of funeral bouquets. Carnation is a herbaceous plant that can reach 31 inches in height.

Carnation has 6 inches long slender leaves. They are usually grayish or bluish green in color and covered with waxy substance. White carnations will change its color after adding food coloring to the water. The flower will change its color after 24 hours.

Dianthus is Latin which for “flower of the gods”. White carnations are inevitable part of wedding bouquets and bouquets prepared for the first wedding anniversary. Carnations are birth flowers for all people that are born in January. These flowers are often used as decoration for tuxedoes.

Bouquets made of pink carnations are traditionally prepared for Mother’s day. Colombia is the greatest producer of carnations in the world. Carnations are national flowers of countries such as Monaco, Spain, Slovenia and Ohio. They are also used as a symbol of different fraternities and sororities.

Carnations can propagate via seeds and plant cuttings. Carnations are perennial plants, which mean that they can live more than 2 years. Carnations also have long lifespan in the vase – they can remain fresh up to 14 days after removal from the ground.
