# Monitoring the SAM       — AgEcon

> An AgEcon analysis says the Southern Annular Mode is expected to dip negative and then return near neutral in the coming weeks, and it is unlikely to affect Australian climate in that period. The piece notes that a negative SAM typically brings dry westerly conditions to eastern Australian cropping areas, and that growers should monitor it during planting.

## Why it matters

Limited expected SAM influence means no strong near-term signal for eastern Australian grain or cotton crops, so there is little price impact.
