The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds—the trade winds—to move from east to west on both sides of the equator across this 60-degree “belt.”

Global Wind Patterns: wind belts of the general circulation. The global wind pattern is also known as the “general circulation” and the surface winds of each hemisphere are divided into three wind belts: Polar Easterlies: From 60-90 degrees latitude.

When air moves in a definite direction, it is called wind. If the winds move from west to east, they are called westerlies. If they move from east to west, they are called easterlies. There are winds because there are differences in pressures.

Air rises over the Equator and is drawn poleward by the pressure gradient. But as the air moves poleward, the Coriolis force turns it westward, so it eventually descends at about a 30° latitude, completing the thermal circulation loop.

The science (and a surprising twist) to a longstanding myth. Like the rotation of a hurricane, water rotates counterclockwise in a bathtub drain in Northern Hemisphere, and clockwise south of the equator, right? Nope. That’s a total myth.

In fact, tropical cyclones — the general name for the storms called typhoons, hurricanes or cyclones in different parts of the world — always spin counterclockwise in the Northern Hemisphere, and spin in the opposite direction in the Southern Hemisphere.

Observations show that no hurricanes form within 5 degrees latitude of the equator. People argue that the Coriolis force is too weak there to get air to rotate around a low pressure rather than flow from high to low pressure, which it does initially. If you can’t get the air to rotate you can’t get a storm.

Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface.

Rare South Atlantic Hurricane Hits Brazil. Hurricanes occur in many places around the world. On March 25, 2004, the first ever recorded hurricane made landfall in the South Atlantic along the Southeastern Coast of Brazil.

The Coriolis force assists in setting the circulation of a hurricane into motion by producing a rightward (clockwise) deflection that sets up a cyclonic (counterclockwise) circulation around the hurricane low pressure.

The “doldrums” is a popular nautical term that refers to the belt around the Earth near the equator where sailing ships sometimes get stuck on windless waters. That is why sailors well know that the area can becalm sailing ships for weeks. And that’s why they call it the doldrums.

These prevailing winds, known as the trade winds, meet at the Intertropical Convergence Zone (also called the doldrums) between 5 degrees North and 5 degrees South latitude, where the winds are calm.

There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig.

The U.S. National Weather Service defines a gale as 34–47 knots (63–87 km/h, 17.5–24.2 m/s or 39–54 miles/hour) of sustained surface winds. Forecasters typically issue gale warnings when winds of this strength are expected.

A squall is a sudden, sharp increase in wind speed lasting minutes, contrary to a wind gust lasting seconds. They are usually associated with active weather, such as rain showers, thunderstorms, or heavy snow.

1 : a strong wind. 2 : a wind of from about 32 to 63 miles per hour (about 51 to 101 kilometers per hour) 3 : an outburst of amusement gales of laughter.

A gale force wind (or gale) is a strong, persistent wind with a minimum speed of 50 km/h (31 mph) and a maximum speed of 102 km/h (63 mph), which are typically associated with coastal regions. Naturally, winds of this wind speeds can be very dangerous and destructive.

Gale, the Bad Princess is a bird in Angry Birds Stella and is the primary villain in the said title, being the direct equivalent to the King Pig from the standard Angry Birds titles.

Gale, wind that is stronger than a breeze; specifically a wind of 28–55 knots (50–102 km per hour) corresponding to force numbers 7 to 10 on the Beaufort scale. As issued by weather service forecasters, gale warnings occur when forecasted winds range from 34 to 47 knots (63 to 87 km per hour).

A gale warning is an alert issued by national weather forecasting agencies around the world in an event that maritime locations currently or imminently experiencing winds of gale force on the Beaufort scale.

The Purple Starling (Lamprotornis purpureus), also known as the purple glossy starling, is a common passerine bird common and widespread in tropical Africa. The species is typically found in scrublands, open woodlands, savannas, and cultivated areas. Adults have a metallic purple head, crown and body.

Here the list of 10 most beautiful birds in the world.

• 8 Bohemian Waxwing.
• 7 Blue Jay.
• 6 Atlantic Puffin.
• 5 Keel-billed Toucan.
• 4 Peacock.
• 3 Flamingo.
• 2 Scarlet Macaw.
• 1 Golden Pheasant.

When bird poop is purple it means that the bird has been feeding on an oversupply of purple-coloured berries. It is uncommon, but still possible that purple poop indicates a digestive infection in the bird.

Purple Martins

Varied Bunting: Medium bunting, mostly purple-blue with red wash on throat, breast, back. Nape and eye-rings are red. Bill is gray and slightly curved down. Wings and tail are purple-blue. Female has brown upperparts with buff underparts.

Eastern Bluebirds

Bluebirds are considered fairly common, but their numbers have declined substantially during the last century. Populations have been given a boost by the birdhouse boxes that have become popular in many parks and backyards.

As early as February – April for the first nesting. Sometimes later if first-time nesters or multiple nesters. What do they use for a nest, and what does a Bluebird nest look like? Bluebirds typically use woven grass, pine needles, straw, hair and sometimes feathers.

Red Cardinal Miracle

Many cultures believe the color blue to bring peace and keep the negative energy away and bluebird live up to their name is this regard. The spiritual meaning of bluebird is joy and happiness. Overall, the bluebird spirit animal almost always means good news.

Near the equator, the trade winds converge into a broad east to west area of light winds. The area is known as the doldrums because there are light winds. This belt of air around the equator receives much of the sun’s radiant energy.

Named from Old English Trade = path, because of their regular course, these winds are the tropical easterlies, northeast Trades in the Northern Hemisphere and southeast Trades in the Southern Hemisphere.

In this page you can discover 3 synonyms, antonyms, idiomatic expressions, and related words for trade-winds, like: trades, prevailing winds and antitrades.

In sailing terminology, windward means “upwind,” or the direction from which the wind is blowing. An island’s windward side faces the prevailing, or trade, winds, whereas the island’s leeward side faces away from the wind, sheltered from prevailing winds by hills and mountains.

The “doldrums” is a popular nautical term that refers to the belt around the Earth near the equator where sailing ships sometimes get stuck on windless waters. As the air rises, it cools, causing persistent bands of showers and storms around the Earth’s midsection.

The Doldrums holds a distinct place in maritime history, having developed a reputation as a potentially deadly zone which could strand ships for weeks on end, causing them to run out of food and drinking water.

The Doldrums are located a little north of the equator, but the effects can be felt from 5 degrees north of the equator to 5 degrees south of it. The trade winds border the Doldrums both to the north and south. Then there are the prevailing westerlies in the higher latitudes and the polar easterlies near both poles.

Get back on course with these three tips to escape the ‘data doldrums’.

1. Before you set sail, know where you are going. Know your destination.
2. Set a time to drop anchor. Establish a series of timelines to help you stay on course and avoid circling back over the same data.
3. Establish an escape route.

Unable to sail and resupply due to lack of wind, crews often ran out of drinking water. To conserve scarce water, sailors on these ships would sometimes throw the horses they were transporting overboard. Thus, the phrase ‘horse latitudes’ was born.

They have pinpointed the coldest, driest, calmest place on earth, known simply as Ridge A, 13,297 feet high on the Antarctic Plateau. ‘It’s so calm that there’s almost no wind or weather there at all,’ says study leader Will Saunders, of the Anglo-Australian Observatory.

Scientists have discovered that the calmest place on Earth is on top of a vast icy plateau in Antarctica. According to a report in the Times, scientists pinpointed a site, known simply as Ridge A, high up on the Antarctic Plateau, several hundred miles from the South Pole.

Breezy is described as a sustained wind speed from 15-25 mph. Windy is a sustained wind speed from 20-30 mph. Sustained winds between 30-40 mph.

Wind chill values will be in the 20s to 30s throughout the day. – at 19 to 24 mph, smaller trees begin to sway. – at 25 to 31 mph, large branches will be in motion, whistling will be heard in overhead wires, and umbrella use becomes difficult if not impossible. – at 32 to 38 mph, whole trees will be in motion.

“Windy” conditions. Sustained wind speeds of 21 to 25 mph, or frequent wind gusts of 30 to 35 mph. ” A Very Low Threat to Life and Property from High Wind.” “Breezy” to “Windy” conditions.

Walking in a 30 mph wind can be tricky, at 40 mph you could be blown off balance and at 60 mph it is almost impossible to walk. The wind speed given by the BBC or local radio station will be at sea level. At 900m above sea level the wind could be blowing about three times stronger than at sea level.

About 140 mph from the side of the car. The more the car weighs, the more wind it takes to flip it.

20-30 is kind of strong breeze and a bit more. 50-60 is hard to hear in but still possible to walk into. You may find yourself leaning into it. It is tiring to walk into and of course excellent to walk behind.
