Trends of Dust Transport Episodes in Cyprus Using a Classification of Synoptic Types Established with Artificial Neural Networks

Table 2

Synoptic classes and their trends for the 25-year period 1980–2005. Classes associated with dust events are in bold, whereas classes with no association to dust events are not in bold; positive trends are shown as POS and negative trends as NEG. The 𝑅² for each class is also shown.
