Current Weather Indicators
An overview of the current weather situation is shown below. The following variables are visualized:
-
-
-
-
- T max: the maximum temperature in Β°C
- T min: the minimum temperature in Β°C
- P amount: the total precipitation amount over the period in mm
- P chance: the precipitation chance in % (only forecast)
- RH max: the maximum relative humidity in %
- RH min: the minimum relative humidity in %
- Wind speed: the average wind speed in m/s
- Wind gust: the maximum wind gust in m/s (only forecast)
-
-
-
The maps show the variable’s average over the period indicated by the cursor bar. The only exceptions are “P amount” and “PET”, for which the total accumulated value is displayed.
TIP: the Current Weather maps can be useful to recognize the onset of the rainy season. Selecting the “P amount” panel and moving the bottom cursor from left to right, it is possible to have an overview of the rainfall observed in the previous month and expected in the next two weeks.
A progressive increase of the amount of rain is likely to indicate the start of the rainy season if observed in all time frames. However, if less rain is expected in the time frame “Next 15 days” or “Days 8-15“, this might suggest the occurrence of dry spells or of a false start of the rainy season. Lastly, high values of precipitation throughout all time frames indicates that the rainy season is currently happening, while the opposite indicates the presence of the dry season.
