Isoline

- Isoline maps are used extensively in meteorology. They normally tell geopotential differences between areas.
- This map was showing the differences between the 6 h forecasts were analysed individually during the first days. On the first day of assimilation, the differences were located mainly over the extra-tropics for temperature, and over Land and near the coast for specific humidity, but these differences were spread (as expected) over the whole globe on the second day.
