Weather: WEEKEND, we have good news! Look what can happen on Saturday 8 and Sunday 9 July…
The latest update confirmed that as of starting Friday, July 7 there will be a change of time: broadening our gaze to the entire hemispheric tableau we can see how a promontory of the vast The African anticyclone will spread from the coasts of North Africa to reconquer the central-western Mediterranean, thus starting the Second heat wave of the season.
The map that we propose below shows exactly the field high pressure (indicated by the letter “TO“) supported by masses of hot air that come directly from the interior of the Sahara desert.
African anticyclone strengthening towards Italy The effects will be felt from Saturday July 8 when we will have stable and sunny weather conditions with warmer weather in a large part of the country (only to report the instability with local storms in the alpine arc) with temperatures well above the climatic averages with peaks towards the 35°C especially in the central regions (Tyrrhenian side).
The subtropical high pressure will also keep us company sunday july 9 guaranteeing almost total atmospheric stability with solar and thermal values more than 35°C in the northern plains and with maximum peaks up to 37°C in the internal areas of the Center (florence risk of temperatures above 36°C).
To make the heat even more unbearable, theembarrassment: gradually warmer air masses within the anticyclone will be charged with high rates of humidity on the long journey across the Mediterranean Sea from the Sahara to Italy; this condition, let us remember, of physical discomfort.
What does this definition mean? Among the best-known biometeorological indices we find theheat index (heat index in English). It is an index calculated to estimate the physiological discomfort caused by the presence of high temperatures and high humidity levels. As always, the key point to remember is that the higher the (relative) humidity, the harder it is for the body to get rid of heat (because it’s harder for sweat to evaporate). The layer of water that remains on the skin clogs the pores and forms a kind of insulation between the body and the environment and, in the most extreme cases, heat stroke can occur.
