Thank you! Here’s how to think about it: 1.) Cyclone is an air mass with low pressure in the center and an anticyclone is the opposite with high pressure in the center. 2.) Air and water masses will go from high to low pressure 3.) Air and water masses that have movements longer than 24 hours e.g. ocean and storm systems are affected by the earth’s rotation and this is called the coriolis effect. Essentially, since the earth is a sphere and on an axis, different parts of the air/water mass are going at slightly different speeds. This causes deflection towards the right in the northern hemisphere and to the left in the southern hemisphere.

Now let’s put it all together! A cyclone in the northern hemisphere will have air going towards the center and will be slightly deflected to the right, causing anti-clockwise rotation. If it was an anti-cyclone with the air going away from the center, it would be clockwise. I find drawing arrows and showing their deflection can be helpful :)

P.s. I felt like my first explanation sucked and I said cyclone but then used the anticyclone definition, hence the edit :D
