March 20 is the day of the vernal equinox, after which the length of the day will gradually become longer than that of the night. On the equinox day the Sun will cross the celestial equator and equalize day and night. That will start an astronomical spring in the northern hemisphere.

Meteorological Spring and Astronomical Spring are two ways of defining the start of spring, but they are based on different criteria. Meteorological Spring refers to the three calendar months of March, April, and May in the Northern Hemisphere (or September, October, and November in the Southern Hemisphere). These months are considered to be spring because they generally have milder temperatures and more rainfall than the preceding winter months, and the days start to become longer.

Across West Africa, millions of people know the arrival of a special seasonal wind: the Harmattan. This dry, dusty wind blows from the Sahara Desert toward the Atlantic Ocean, shaping the weather, the sky and daily life during the cool, dry season. When and Where Does the Harmattan Blow? The Harmattan is most common from late November to March, especially in:

In parts of western North America, there is a famous wind that can turn a freezing winter day into a mild, spring-like afternoon in just a few hours. This wind is called the Chinook, often nicknamed the “snow-eater” because of how fast it melts snow. Where Do Chinook Winds Blow?

If you visit the Adriatic coast in winter, you might meet one of Europe’s most dramatic regional winds: the Bora. It is a cold, dry and often violent wind that can transform calm coastal weather into a rush of icy gusts in a matter of hours. Where the Bora Blows The Bora is best known along the northern and eastern Adriatic Sea, especially in:

Solar eclipses occur when the Moon passes between the Earth and the Sun, casting a shadow on Earth. However, not all solar eclipses are the same. There are four main types of solar eclipses, each with unique characteristics: 1. Total Solar Eclipse A total solar eclipse happens when the Moon completely covers the Sun, as viewed from Earth.

Europe does not have a single continent-wide authority for naming storms. Names are assigned by national meteorological services that coordinate in regional groups. When a storm is expected to cause significant impacts, the first service to issue a high-level warning uses the next name from its list and neighboring services adopt it.

The years 2026 and 2027 will bring several spectacular solar eclipses visible from different parts of the world. Here’s what to expect: 2026 Solar Eclipses February 17, 2026 - Annular Solar Eclipse An annular solar eclipse will occur on February 17, 2026. During an annular eclipse, the Moon is too far from Earth to completely cover the Sun, creating a “ring of fire” effect.

Icy underwater bubbles are one of the most curious natural phenomena. In the Canadian province of Alberta, there is Lake Abraham, which is known among scientists and nature lovers because of an unusual phenomenon: a large number of ice bubbles that have frozen under water. These fantastic circles are actually made up of methane bubbles.

“Feels like” temperature (also called apparent temperature) is an attempt to translate weather conditions into how warm or cold they tends to feel on exposed skin. It is not a direct measurement from a thermometer: it’s a calculated value that usually combines air temperature with humidity and/or wind. In most forecasts and weather apps, “feels like” is computed using one of two different indices depending on conditions:
