ERJ-170 flight crew reported a hard landing that may possibly have been caused by jet blast or wake turbulence.
Approach was normal and about 40 feet AGL noticed we were looking steeper than normal. Not sure if it was thermals; wind change; or what. Was expecting the FO to flare and arrest the descent rate for touchdown but she didn't or didn't enough. Hit the runway hard and didn't realize we bounced until resettled a second or maybe 2 later. Slowed airplane down and taxied to the gate where after parking; called Maintenance for a hard landing inspection since I figured it was close to or over the 2.0 G limit.Debriefed about flaring earlier and didn't seem like she noticed the increased descent. She kept asking what happened. I gave her some possibilities but didn't know for sure since I was looking outside that close to the ground. I don't know what our actual descent rate was at touchdown but seemed like we didn't flare at all. Some people flare later than others so I didn't really have time to react when she didn't. In the future I would try to be more proactive and not get complacent even though she landed fine the day before and had been on the line for a year or so.
Possible hard landing event on Runway 12 in MIA. There were no sink rate" warnings. After the aural 50 feet; it felt as if the aircraft lost all energy. In the crew debrief; we were unable to point to an exact reason of what happened. One explanation could be from wake turbulence/jet blast from other aircraft pulling onto and taking off from Runway 8R. Maintenance was immediately notified and aircraft was returned to service after inspection."
