6 dot points across 6 inquiry questions. Click any dot point for a focused answer with worked past exam questions where available.

What is the evidence that the climate is changing, and how do we distinguish natural variability from human-driven warming?

Evaluate the evidence for recent climate change and assess the relative roles of natural and anthropogenic causes
A focused answer to the H2 Geography outcome on climate change. The lines of evidence for recent warming, natural forcings, the enhanced greenhouse effect, and how attribution distinguishes human from natural causes.

How does the way the Earth receives and redistributes solar energy create the conditions for tropical weather and climate?

Explain the global energy balance, the latitudinal energy surplus and deficit, and how the resulting atmospheric circulation shapes tropical climates
A focused answer to the H2 Geography outcome on the global energy balance. Insolation, the latitudinal surplus and deficit, the greenhouse effect, and how energy transfer drives the tropical atmospheric circulation.

Why do large parts of the tropics experience a seasonal reversal of winds and rainfall, and how does the ITCZ control where rain falls?

Explain the migration of the Inter-Tropical Convergence Zone and the mechanism of the monsoon, and account for the resulting wet and dry seasons
A focused answer to the H2 Geography outcome on the monsoon and the ITCZ. The seasonal migration of the convergence zone, differential heating of land and sea, the Asian monsoon reversal, and the wet and dry seasons it creates.

Why do tropical cyclones form only under certain conditions, and why are their impacts so uneven between places?

Explain the conditions for tropical cyclone formation and structure, and assess why the scale of their impacts varies between locations
A focused answer to the H2 Geography outcome on tropical cyclones. The formation conditions, the structure of eye and eyewall, the hazards of wind, storm surge and rain, and why impacts differ with vulnerability and resilience.

What processes generate the heavy, often convectional rainfall that characterises the humid tropics?

Explain the formation of convectional, orographic and convergent rainfall in the tropics and the conditions that produce thunderstorms and intense rain
A focused answer to the H2 Geography outcome on tropical rainfall. Convectional, orographic and convergent mechanisms, atmospheric instability and the lapse rate, and how thunderstorms and squall lines form in equatorial regions.

How and why does the climate of a city differ from its rural surroundings, and what does this mean for tropical cities?

Explain the causes of the urban heat island and other modifications of the urban atmosphere, and evaluate strategies to mitigate them
A focused answer to the H2 Geography outcome on urban climates. The causes of the urban heat island, modifications to wind, humidity and rainfall, and the effectiveness of mitigation strategies in tropical cities such as Singapore.
