Temperature and dew point
The gap between the two curves shows how dry the air is. When they touch, there is dew, mist or frost.
Wind and gusts
The pale band runs from the average wind to the gust of the moment. The wider it is, the more turbulent the air. Anemometer 15 m above the ground.
Atmospheric pressure
Reduced to sea level (station at 311 m), so it can be compared with weather maps. It is the slope that counts, not the value. A rapid fall heralds bad weather. A clear rise heralds clearing skies.
Solar radiation
The energy received per square metre. The shape of the curve says more about cloud cover than any word.
Rain
Intensity measured at each reading, in millimetres per hour.
Where the wind comes from
Share of time spent in each direction over the period, weighted by wind strength.
What lies ahead.
Everything above is measured at the camp. What follows is calculated by a numerical model on a grid of about eleven kilometres, which knows neither the valley nor the lake. Take it as a trend, not a certainty.
The barometer and the wind
The only forecast on this page calculated at Mushuau-nipi, from Mushuau-nipi, using the pressure and the shift of the wind measured on site over the last three hours.
Forecast temperature
The next twenty-four hours, hour by hour.
Probability of precipitation
Chance of precipitation in each hour, according to the model.
Forecast wind
The pale band rises to the expected gust. The model calculates the wind at 10 m, the standard height. The camp anemometer is at 15 m and therefore reads about 7% stronger. The difference is real, not an error.
The season in numbers.
Here is the station’s record since it was installed, day by day, with the extremes, the onset of frost, the course of a typical day and the gap between measurement and the numerical model. The raw data can be downloaded at the bottom of the section.
Daily temperatures
The band stretches from each day’s minimum to its maximum and the line follows the mean. You can watch autumn slip gently below zero.
Solar energy and day length
The first chart gives the energy received each day (in watt-hours per square metre), the second the day length calculated for 56.4° N. In October, the day shortens by about six minutes from one day to the next.
Mean pressure and rain, day by day
Pressure reduced to sea level. The troughs mark passing lows, often accompanied by rain.
A typical day, hour by hour
Averages over the last 30 days for each hour. The range says something about the sky, since overcast days vary little.
The season’s wind rose
Share of time spent in each direction since installation, by wind strength. The darker shades are the strong winds.
The station versus the model
Temperature measured at the camp and archived temperature from the Open-Meteo model, hour by hour over 14 days. The mean difference (the bias) shows whether the model sees the camp as warmer or colder than it is.
