After confirming his pole position, Hamilton celebrated with local fans by punching the air and showing off the back of his helmet.
"I think some of it is still a mystery but I think there are a lot of areas that we have understood", Hamilton said.
Ferrari must better Mercedes' score in Brazil this weekend by 13 points or more if they want the title race to go to the season finale in Abu Dhabi.
In the end, the wet weather stayed away, and Hamilton did what he always seems to do, pulling a lap out of nowhere to claim his 10th pole of the season when it was Ferrari and Sebastian Vettel who seemed to hold the advantage. It is a odd thing to say, but Hamilton has never tasted victory in the race immediately after taking home the title on the four previous occasions. "I think we got the vehicle where it is happiest, and the balance was good in qualifying throughout, so we'll see".
Hamilton's comfortable margin over rival Sebastian Vettel in the Drivers' championship enabled the Brit to conquer his fifth world title despite a lowly fourth-place finish at the Autodromo Hermanos Rodriguez.
"We tried to get a quicker lap on the soft tyre in Q2 but just missed out", he added.
"The seasons are getting longer, and the off-time is getting shorter, so from a competitor's point of view the turnaround is short".
Russian Federation raises North Korea sanctions at UN Security Council
In Seoul, South Korean presidential spokesman Kim Eui-kyeom said that his government doesn't believe U.S. It also has returned the remains of US troops killed in the 1950-53 Korean War.
"There's a drivers' championship, but if you go to any team they're probably going to say this is more important for them - the constructors' championship more than the drivers".
Ricciardo, however, will start five positions behind because of a penalty after his team had to replace his turbocharger for the sixth time this season.
"I'm confident the auto has a good set-up for the race".
Ocon was attempting to unlap himself on the run to Turn 1 as Verstappen led, with the Force India going around the outside but not getting the move done cleanly.
Magnussen's auto also shed a wing mirror during the session.
Charles Leclerc's Q2 lap was something very special indeed.
Antonio Giovinazzi, who will replace Ferrari-bound Leclerc next season, took Marcus Ericsson's vehicle and was 13th fastest in the opening session. The strategy had some logic behind it as it means Ferrari will start the race on the soft compound - which should be the better race tyre - but had a downpour hit just after they came in for the tyre change, both cars would have been caught on track with the wrong tyre.
