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.

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.

“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:

Fog is not just a simple weather phenomenon, it’s a scientific masterpiece. From the scientific point of view, fog is the accumulation of water in the air and the further formation of little condensation products of water vapor. Moreover, the lower the temperature, the more ice crystals are there in the fog instead of water drops.

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.
