A-level Water and Carbon

A blackout after a blizzard is weather. The reason there is snow to melt into the reservoir is a closed budget of stores and transfers.

Click the divide. Source, tributary, confluence, mouth — one budget with a rim.

Rain is the input. The river’s reply has a rising limb, a peak, a lag, a falling limb.

A UK upland nival/pluvial mix vs the Mississippi: the same year, different graphs.

Fast stores and slow stores. The fossil-fuel tap is a human transfer from slow to fast.

The Walker cell can flip. El Niño is a warm pool shift, not a personality. UK weather language stays honest.

A Chalk well in Yorkshire and an Ogallala centre-pivot in Kansas both drink a store you cannot see. The water table is a surface, not a underground lake.
