El Nino Watch
Scored from the mean temperature of the coldest month (ERA5 1991-2020), with frost days and yearly snowfall in the note.
Hazards
The coldest month mean summarises how hard winter is: heating needs, frozen roads, snow clearing. Frost days = days with a minimum below 0 °C. Snowfall is in cm of fresh snow per year.
Cold is a real hazard for health, housing (insulation, heating fuel) and daily life, and a big change for anyone used to the tropics.
| Coldest month mean | Exposure |
|---|---|
| >= 10 °C | 0 very low |
| 3 to 10 °C | 1 low |
| -3 to 3 °C | 2 moderate |
| -10 to -3 °C | 3 high |
| < -10 °C | 4 very high |
Exposure scale: 0 very low, 1 low, 2 moderate, 3 high, 4 very high. Higher = more exposed. The colour of the matrix cell follows the same scale.
