They are characterized by a distinct seasonal climate, with strong, long-lasting frost in winter and extremely hot summer, in combination with very low annual precipitation of less than 100 mm. The temperature of the cold winter deserts and semi-deserts fluctuates between -45°C and +50°C.

Some deserts are near the equator where the air is very dry. Some deserts are in the middle of a continent. By the time the wind gets there, it has little moisture. If rain falls it stays dry in deserts because the sand absorbs the water.

Temperate deserts of continental regions have low rainfall and strong temperature contrasts between summer and winter. Even at intermediate elevations, winters are long and cold, with temperatures falling below 32F (0C). Under the Koppen-Trewartha system, this is true desert, BWk.

The Mojave and Sonoran Deserts are examples of temperate deserts.

The world’s deserts can be divided into five types—subtropical, coastal, rain shadow, interior, and polar. Deserts are divided into these types according to the causes of their dryness.

The great desert was born some 7 million years ago, as remnants of a vast sea called Tethys closed up. The movement of tectonic plates that created the Mediterranean Sea and the Alps also sparked the drying of the Sahara some 7 million years ago, according to the latest computer simulations of Earth’s ancient climate.

Geographically speaking, most deserts are found on the western sides of continents or—in the case of the Sahara, Arabian, and Gobi deserts and the smaller deserts of Asia—are located far from the coast in the Eurasian interior. They tend to occur under the eastern sides of major subtropical high-pressure cells.

The Sahara is the largest hot desert in the world, and the third largest desert behind Antarctica and the Arctic, which are both cold deserts.

Their traditional lifestyle has adapted to these extremely arid conditions. Their nomadic lifestyle means they do not settle in one area for long. They have herds of animals which are adapted to living in desert conditions, such as camels. Their tents are built to allow air to circulate within them, keeping them cool.

Deserts are perhaps one of the most difficult places to live. Because humans need so much water, surviving in deserts is very difficult. Not only is it difficult for humans to survive in deserts – it is also hard for animals, plants and other forms of life to live.

Lack of water, the most evident disadvantage to deserts in general, results from the combined effects of insufficient rainfall and rapid water evaporation by nearby land masses. The rate of rainfall rarely exceeds the rate of evaporation, and it is not uncommon for rain to vaporize even before hitting the ground.

According to estimates, the Sahara’s entire population probably equals less than two million people, including those who live in permanent communities near water sources, those who move from place to place with the seasons, and those who follow the ancient trade routes as permanent nomads.

The sand dunes of the desert are big that they reach heights of 600 feet. Life in the Sahara Desert is very difficult due to its climate. It receives less than 3 inches of rain every year. The Sahara Desert is the hottest place in the world with the temperature reaching up to 57.7 degree Celsius (135.8 degree F).

That’s because temperatures in the Sahara can plummet once the sun sets, from an average high of 100 degrees Fahrenheit (38 degrees Celsius) during the day to an average low of 25 degrees Fahrenheit (minus 4 degrees Celsius) during the night, according to NASA. …

Why Does It Snow in Desert? A high pressure formation in Europe, causes the cold air from the Artic to be pulled down, which makes its way through southern Europe landing in the Sahara desert. This cold air then rises to the elevation Ain Sefra, where it causes the snowfall.

Snow is a very rare occurrence in the Philippines. This one looks more like pieces of ice. The snowfall in Benguet, Philippines is an anomalous phenomenon. Snow can be called frozen rain falling on the ground in winter in countries where the temperature at this time of year is below zero.

Snow in Dubai? It’s highly unlikely that we’ll see or hear of it again for a few years, but in 2009, it did actually snow in Ras Al Khaimah, the UAE’s most northerly Emirate.

Weather Today in Dubai – Current Conditions The current temperature in Dubai right now is 95°F (35°C). The wind speed is approximately 2 mph (light air), blowing from south-southwest. The visibility today is good.

Dubai has a subtropical hot desert climate (BWh) whereas New Delhi has a humid subtropical climate with dry winters (Cwa). Dubai is in or near the subtropical desert biome whereas New Delhi is in or near the tropical very dry forest biome. The mean temperature is 1.8 °C (3.2°F) warmer.
