Background
|
Each year, CLEVER°FRANKE (C°F) publishes a weather chart. In these annual charts, we explore methods to visualize last year's weather. CLEVER°FRANKE has a special affinity with the weather; the names CLEVER and FRANKE have been combined with the aid of the degree symbol. A reference to the astronomer Anders Celsius (C°) and physicist Daniel Fahrenheit (F°). |
This degree symbol served as the basis for the design of our visual identity: two researchers within the same field, found different approaches and references. Something definitely recognisable in the personalities of the founders of CLEVER°FRANKE. |
Global ranking of countries based on average temperature (1962 - 2012)
|
This year we examined the global weather data of ±30,000 weather stations over the past 50 years. This is based on the analysis of 736,995,534 global measurements of the National Climatic Data Center measured in the last 50 years. Among other things, we have found Djibouti to be the hottest country in the world. |
The Netherlands takes place at 151 in the ranking of ‘warmest’ countries with an average temperature of 10.1°C / 50.3°F. In terms of rainfall, the Netherlands claims place 101 as rainiest country with 1.77 mm per day precipitation. In terms of wind speed, the Netherlands ranks amongst the windiest countries at place 13 with an average wind speed of 18.1 km/h. |
Social media weather sentiment vs. KNMI weather data
| For 2012 we focused on the relationship between weather data provided by the KNMI (Royal Netherlands Meteorological Institute) and the sentiments in social media about the weather. Is the way people rate the weather on the internet in accordance with the meteorological facts? To analyse this, we have used 714,843 messages concerning the weather in this chart. The messages were collected from a variety of websites, social media platforms and internetfora. This data was provided by Finchline, a company specialized in social media monitoring. Our weather chart of this year provides several interesting observations; sunshine is prominent in the way most people rate the weather. The correlation between sunshine and weather sentiment is stronger than the correlation between weather rating and sentiment. Overall, the Dutch weather is predominantly rated negatively (58%). Only in April and March people rated the weather mostly positive. Along with the increase in general use of social media in 2011, the amount of messages about the weather rose throughout this year. As the months passed, people rated the weather more negatively, especially in the month December. |
The weather concerns us mostly on the mornings of working days: the amount of messages peaks between 7:00 and 8:00 AM and during lunchtime. During the weekend, we tend to write less about the weather.
The Dutch generally don’t deceive themselves about meteorological circumstances: the accordance between positive and negative messages about the weather differs only 16.5% from the weather rating based on the data of De Bilt, the Netherlands.

CLEVER°FRANKE Weather Chart 2011
|
In this years edition we tried to show the most prominent weather condition for a specific day with just one glance. We did this by showing the angle of the ‘pie piece’ in relation to the other weather elements and the deviation in comparison to the absolute average of 2010. |
This way each day of 2010 can quickly be defined as sunny, rainy or windy; something the Dutch love to complain about! » C°F Weather Chart Shop |
