We know California is very , very wry , decently now , but just how ironical ? ironical enough that the “ rainfall debt ” the state has been steady heap up in the past three days is now equal to a full class of average rainfall .
NASA Goddard put together a survey of the last 36 yearsof California rainfall and found that the “ rain debt ” now came in at a full 20 column inch — or the average rainfall the country receive in a year .
It ’s a sign of just how deep the drought has gotten , but it ’s also a good monitor of why — when we ’re talking about ending a drouth — we’re not just talking about the amount of water , we ’re also talking about the timescale it come in .
Drought has a stacking effect with the drought of one year building off the drought of the class prior . To some degree , drier and wetter years run to even out over time , but the longer the drouth go on and the grown that rain debt becomes , the harder it is to ever catch back up to that equilibrium .
