India: climate and the monsoon
A first-attempt learner with school-level reading, basic arithmetic and little retained geography; later chapters assume the earlier physical-process chapters have been studied. Basic literacy remediation and Geography optional are outside this estimate.
Includes
- Selected primary readings and their diagrams/maps
- Brief comparison notes and process/map sketches
- Available mapped practice, mistake review and one initial recall review
Separate time needed
- Later spaced revisions and full-paper mocks
- Reading every optional exercise or every source book in full
- Excludes reteaching global atmospheric physics, operational forecasting training and a continuing daily weather-reading budget.
Editorial planning estimate; not learner timing data
- Differential heating, the monsoon trough and the northward shift of the ITCZ
- Tibetan plateau heating, withdrawal of the subtropical westerly jet, tropical easterly jet, Somali jet and Mascarene high
- Arabian Sea and Bay of Bengal branches; orographic rain on the Western Ghats and the north-east
- El Nino, La Nina and the Southern Oscillation; Walker circulation; link to Indian monsoon rainfall
- Indian Ocean Dipole: sea-surface temperature difference between western and eastern tropical Indian Ocean; can modulate El Nino's effect
- Ocean Mean Temperature and other IMD long-range forecast predictors
