variability

While there are clear guidelines as to what you are looking for, Dr Wong says there is still a lot of variability.

Like heatwaves on land, sea temperatures are affected by natural variability and short-term weather.

That's why the country's climate is so changeable and that variability also makes mapping some climate changes more difficult.

But the way the teams have prepared their cars for the race adds extra potential for variability.

"The breakdown is systemic - it begins with planning that often doesn't account for future climate variabilities, gets exacerbated by poor execution and is compounded by weak enforcement of regulations," Mr Kukerja says.
