The wet-bulb temperature is an important measure of the Earth’s climate and is used to determine the risk of heat stress and heat-related illness in humans and animals. The wet-bulb temperature is the temperature that a thermometer would show if it were covered in a wet cloth and exposed to the air.

In order keep safe when it’s hot outside, it’s important to know how hot it really feels. Scientists created something called the Wet Bulb Globe Temperature or WBGT to measure the heat stress in the air. Imagine you have three thermometers: a regular one, a wet one, and one inside a shiny black ball.

June 21st is #ShowYourStripes day, a global initiative aimed at raising awareness about climate change. The day is named after the iconic “climate stripes” graphics, which depict the warming of the earth’s surface over time using a simple color scheme, with 🟦 blue representing cooler temperatures and 🟥 red representing warmer temperatures.

Meteorological summer and astronomical summer are two different ways of defining the summer season. Meteorological summer is defined by the three warmest months of the year in a particular region, typically June, July, and August in the northern hemisphere and December, January, and February in the southern hemisphere. This definition is based on the annual temperature cycle and is primarily used by meteorologists and climatologists for weather forecasting and climate analysis.

In the first dates of May we will be able to watch the Eta Aquariids Starfall. The peak of its activity will be on May 6-7, but overall the shower is visible from about April 19 to about May 28 each year. It will be seen brighter in the Southern Hemisphere, although the residents of the Northern half of the Earth will also be able to watch the starfall.

Lenticular clouds are one of the most beautiful natural phenomena. When you first see them in a photo, it’s hard to believe that this is a real shoot, not a photoshop. Lenticular clouds are quite rare and can be observed mainly in mountainous areas. Most often they are recorded in the United States, Kamchatka, and near Mount Fuji in Japan.

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.
