A few days ago, France suffered the hottest scorching episode ever recorded. Meanwhile. However. In addition, The Météo-France public agency had classified 16 departments On a heat heat and dozens of others on orange alert. For example, This phenomenon is one of the nine meteorological events Let the organization monitor daily. In addition, namely violent wind, rain-rowing, floods, thunderstorms, snow-Verglas, avalanches, heat wave, very cold and vague-submersion.

Every day. Similarly. Meanwhile. Moreover, Météo-France publishes a “double card” of the country, one with forecasts for the same day and another with those for the next day. Moreover, The card “is updated daily Twice a day, at 6 a.m. For example, and 4 p.m. Therefore, and more regularly if the situation requires how vigilance levels established météo-france? new it, “said the agency on its website. For example,

Sent to the media. Therefore. Meanwhile, public authorities how vigilance levels established météo-france? Moreover, new and the population, this double card is used to alert on how vigilance levels established météo-france? However, meteorological dangers potential To allow everyone to protect themselves. Nevertheless, It was created in 2001, in response to the devastating storms of 1999. Similarly, To make it more accessible. a code of four colors is used where each is carrying a different alert level: green. no particular vigilance; yellow, be careful; Orange, strong vigilance; Red, absolute vigilance.

Decisions in the channel

Present 24 hours a day. 7 days a week. all year round. “Météo-France forecasters are mobilized well upstream From the dangerous meteorological episode “, specifies Damien Griffaut, deputy director in charge of operation. Eighty-five forecast models are established at least four days before a meteorological how vigilance levels established météo-france? new episode. They are then analyzed by the forecasters who determine a” privileged forecast scenario “.

Meteorologists “slightly vary the initial conditions. the setting of the model to have the range of possibilities in terms of scenario and thus get an idea of the uncertainties”, adds Pierre Tabary, deputy director of the operations management for the forecast and the leader of the vigilance project. The card is gradually evolving to always highlight The latest forecasts. Additionally,

The levels of vigilance are established according to different criteria according to phenomena and departments. This includes forecasts. the degree of sensitivity of a territory in the danger in question as well as “other economic elements” such. as local vulnerabilities. For example, if a soil how vigilance levels established météo-france? new is already full of water, the level of rain-rumming will be revised upwards. Likewise. if precipitation has weakened the trees. it will be taken into account in the evaluation of a how vigilance levels established météo-france? new vigilance violent winds.

Knowledge how vigilance levels established météo-france? of the weather beyond borders

This increased knowledge of the territory is based on various observations tools: barometers. thermometers, radars, satellites. They do not only scrutinize events in France. but also throughout Europe and Africa, where different winds and sea currents occur. They transmit their information to meteorologists every five minutes.

Météo-France is also in regular communication with state services to be constantly aware of what’s going on on. the field. During an orange. red situation. new cards are published outside the fixed hourswhich can be the subject of meetings with the authorities to inform. them in detail about the dangers how vigilance levels established météo-france? new incurred.

However, a maximum rate of “non-detection of situations deserves orange or red alert” is authorized. It is around 2 % and that of false alarms, around 16 %. Each orange. red alert emitted during the three. how vigilance levels established météo-france? new four months sold, the relevance of the level of how vigilance levels established météo-france? vigilance is verified. There pedagogy And the prevention of dangers are at the heart of the work of Météo-France.
