Rain
In meteorology, precipitation is any and all product of the condensation of atmospheric water vapor, most often from clouds, which is pulled down by gravity and deposited on the Earth’s surface. The main forms of precipitation include rain, snow, and hail
Rain is liquid precipitation (They are water droplets) and the most frequent type of precipitation on Earth.
The representation of rains in the graph is illustrated by means of a bar graph in blue. Inside the graph we have a bar in “T” that represent the possible errors both for more, and for less for the rain variable.
Air Humidity
Air humidity in simplified terms, is the amount of water in the form of vapor that exists in the atmosphere at the moment in relation to the total maximum that could exist, at the observed temperature.
Air humidity, is illustrated by means of a blue line within the graph, which will oscillate depending on the expected value for each day.
ETo Reference Evapotranspiration
This map shows the reference evapotranspiration (ET0) in millimeters (mm) according to FAO standards (Food and Agriculture Organization). The values are calculated based on meteorological variables (radiation, temperature, humidity, wind speed) for a well-irrigated surface and completely covered by the crop. The term evapotranspiration describes the loss of water from a vegetated surface through the combined
Reference evapotranspiration, is represented in the graph by means of a green line within the rain forecast bar.
Probability of rain
Probabilities of precipitation (as well as other parameters) are calculated from a set of model tests. The probability is the frequency with which precipitation occurs in these different weather forecast calculations. This calculation is usually done for an area (grid cell).
Probability is the chance that an event has to occur. For the rain variable, probabilities greater than 70% should be taken into account, and values below 70% should be disregarded because they have low chances of this event occurring in the future.
Convergence of meteorological models
Convergence – It is the difference between various maximum and minimum model results. This is an approximation of how much the different model simulations are “in agreement”.
- High convergence: event is more likely to occur.
- Low convergence: case is still uncertain.
rainSPOT® and Rain Distribution (mm) – 20km Radius
The rainSPOT shows the precipitation in the vicinity of the selected place for the time interval (e.g. hour) preceding the indicated time. If the rainSPOT shows 3-hour intervals (e.g. 08:00, 11:00, 14:00…), the rainSPOT for 11:00 shows the precipitation from 08:00 to 11:00.
The rainSPOT works like rainNOW, with an aggregation of grid cells so that the selected place is in the center. The position of the place is not always in the center of the grid cell, which means you may be a few meters or kilometers away from the center of the place according to the model resolution. This way, you are always in the center or near the center – no matter which place you choose, even in the mountains or at sea. The meteoblue system with global coverage allows you to have a regional view for any place in the world.
