Quand est-ce que les prévisions meteoblue sont mise à jour?

La prévision meteoblue a 3 types de mise à jour :

1. La mise à jour du modèle continental : au moins deux fois par jour ;

2. La mise à jour du modèle régional : au moins deux fois par jour, après le calcul du modèle continental;

3. L'adaptation locale : lors de la demande, après la sélection du lieu.

Les CARTES mises à jour sont basées directement sur les modèles, normalement 2 fois par jour. L'horaire de mise à jour donné est le temps - en UTC - de l'initialisation (quand le calcul commence) du modèle utilisé. 

Les données POINT sont mises à jour au moins 4 fois par jour. L'horaire de mise à jour est la conclusion du dernier calcul utilisé, et donné en temps local (valide à l'emplacement choisi), et montré au fond de la page de prévision détaillée du POINT.
Les Météogrammes sont mis à jour 2-4 fois par jour, en fonction de la région choisie. L'horaire de mise à jour est la conclusion du dernier calcul utilisé, et donné en UTC, montré en haut de la page. UTC est utilisé pour faciliter la comparaison, surtout pour les services professionnels.

Est-ce que une nouvelle version de la page web meteoblue n'affiche pas correctement?

Solution simple: pressez « shift ñ » et « recharger la page » simultanément. Si ceci ne résout pas le problème, il est causé par le proxy-serveur de votre fournisseur d'Internet, que peut guarder des vieux dossiers CSS pour réduire le trafique. Les dossiers CSS sont responsables pour aficher le site internet, et les vieux dossiers peuvent causer les problèmes de temps en temps. Normalmente, les proxy-serveurs effacent les vieux dossiers CSS dans des intervalles réguliers, et cela permet à la nouvelle page d'être correctement chargé.
Si vous avez les problèmes d'affichage néanmoins, s'il vous plaît nous contacter .

Why do forecast latitude and longitude not fit my location?

For each desired forecast location we extract the closest forecast point from our weather model for Europe. Currently, the distance between desired location and forecast point can be up to 8.5km. Particularly in the Alps this can imply large differences in elevation which of course affect the temperature. For this reason we provide the model point's co-ordinates as well as its elevation on our forecasts. See below for how to adjust the temperature forecast at your location.
Soon we will extract our forecasts from our high resolution weather model for Central Europe where possible. Then the distance between desired location and closest forecast point will be below 2.2 km. We will also apply correction algorithms, which are already available for our commercial customers.

Pourquoi les meteoMaps ne couvrent pas mon pays entière?

Nous produisons nos propres prévisions et faisons les meteoMaps utilisant les modèles détaillés de prévisions météorologiques. Ces modèles couvrent certains régions d'intérêt (domaines). Quelques domaines (comme le NMM-03 pour l'Europe Centrale et le NMM-18 pour l'Afrique subdésertique) ne couvrent pas le continent entier, parce que quelques régions ont moins de besoin de prévisions météorologiques de haute Opens internal  link in current windowrésolution. Par conséquent, quelques régions ne seront pas couvertes par des cartes en détail.
Nous obtenons beaucoup des demandes pour des cartes régionales. Nous prévoyons une augmentation de notre gamme de meteoMaps pour couvrir plus des régions en détail, et ferons cela une fois que nous avons une bonne solution pour présenter plus des meteoMaps dans la navigation. Voyez notre Opens internal  link in current windowNouvelles .  Dans le entretien, vous pouvez faire des cartes plus régionales pour votre régions utilisant   Opens internal  link in current windowmyMapServer .

What happened to the astronomy seeing prediction?

myMapServer offers an experimental astronomy seeing prediction. Register / log in and navigate to "Astronomy Seeing". Select a location on the map, and click "Make Map". The seeing prediction for your selected location will be produced. Please be patient, as this may take up to a minute to compute.

Seeing2 and seeing1 are two different models to calculate visibility. They differ in the way how atmospheric density gradients influence visibility. Seeing2 gives more weight to the effect of density fluctuations, and is more likely to indicate air "flickering" due to turbulence.

Please add a meteogram for my place

We have streamlined our map production system which was crucial as we produce several ten thousand maps each day. Meteograms are used unevenly, which in the past led us to produce a large number of meteograms that nobody looked at. At the same time we received numerous requests to add meteograms for many different and often very small places.


This was one of the reasons for us to create myMapServer. myMapServer allows you to produce meteograms for any place in Europe, Africa, and South America.

Can I have more than 50 credits per day in myMapServer?

myMapServer is limited to 50 credits per user per 24 hours to control server load and guarantee reasonable response times of this free service. However, we will give you 200 credits per day provided that you agree to the following beta tester conditions:
  • you send a request to info(at)meteoblue.com with the title "myMapServer BETATEST" stating that you agree to these conditions, including your contact details (first and last name, address, and telephone); we may use this data solely to contact you.
  • you do not use myMapServer for commercial purposes.
  • you complete and return questionnaires that we may send you from time to time within 7 days.
  • you agree to test myMapServer once in a while by following simple instructions.
  • you report bugs and other obervations that will help to improve myMapServer to info(at)meteoblue.com with the title "myMapServer BETATEST: Keyword". Keyword is a keyword summarizing your comment.

We appreciate your support!

Why was the temperature forecast wrong today?

Fog can affect temperatures locally and is not easy to predict. meteoblue weather models include fog but sometimes "miss" it: For example, in early January 2008 Swiss temperatures in the Mittelland (Fribourg - Bern - Olten) remained around freezing, whilst meteoblue forecast temperatures increasing to 4-8°C. What had happened? Persistent fog had been slow to dissipate, keeping the sun from warming the ground. The meteoblue weather models predicted rapid fog dissipation, and therefore rising temperatures. We are routinely fine-tuning our weather models and expect further improvements with local fog forecasting.

My place is at higher (lower) elevation than the forecast. How do I adjust the forecast temperature?

The meteoblue local forecast shows you the elevation of the region for which the temperature and wind forecasts are valid. To adapt the forecast to your own location, subtract 1°C for every 100 m of elevation, or 0.5°C per 100 m of elevation if the air is saturated (>99% humidity). Under temperature inversions (stable low hanging clouds with no wind for several days - typical for the winter), temperatures will rise with elevation, and be higher above the cloud layer than below.

myMapServer login does not work.

Here are tips that solve 99% of problems our users report:
  1. Make sure you enter your COMPLETE username and password. The username has to contain your complete email address, including provider name and country or global domain code.
    • Username Examples:
    CORRECT: user@provider.com.
    WRONG: user@provider
    WRONG: user
  2. Observe upper and lower case spelling. The myMapServer login system is case sensitive, that is "your.name" is different from "Your.Name".

  3. Make sure you have an up-to-date version of the Java Runtime Environment (JRE). You can download this from http://www.java.com/en/download/manual.jsp.

  4. Your browser may have cached an invalid user id or password. Delete  cached passwords and try again.

What does this myMapServer error message mean?

If after clicking "make Map" you get a message of the form
%subscipt range values of the form low:high must be>=0,<size,with
low<=high:% execution halted at:ION_MAP_REQUEST

  1. Go back to the previous page (on which you have clicked "make Map") and refresh the page.
  2. Make sure you have an up-to-date version of the Java Runtime Environment (JRE). You can download this from http://www.java.com/en/download/manual.jsp.
  3. In rare cases this message reflects that the server is highly loaded. Try again a bit later.
