Speculation: Big Planet's Weather

For a big terrestrial planet** with the following attributes:

1) One bar surface pressure
2) Twice Earth's diameter (x4 Earth's area)
3) 1.5G surface gravity (x6 Earth's mass)
4) Earth-like atmospheric composition
5) Earth-like solar illumination
6) 75/25 water/land area split

What would the weather generally manifest as? More atmospheric
convection (Hadley?) cells? Bigger, beefier hurricanes on the broader
oceans? How would the atmospheric compression due to the higher gravity
affect normal vertical circulation, or wouldn't it matter?

**Yeah, the planet may not be possible (I'd wonder why it didn't turn
into a gas giant), but run with it for the thought experiment.
Thanks for any input,

I'd think offhand that obliquity and the rotation period would also be major
determinants of weather.

Oh, right. Tilt: 25 degrees. Day: 30 hours.

Park the thing in Mars orbit and I'd expect all water surface. Okay I'm
ignorant so it might have been 5% or even 10% land.

Right. However, this big planet has 25% land and terrestrial levels of
sunlight. What would the weather be like?

"Exciting" ;-)
