a hurricane was approached by a smaller and weaker Low Pressure system? Would it change course?? Would it "swallow up" the smaller Low and strengthen? What would happen if a  hurricane is approached by a High Pressure system?? Would it change course or weaken??

Sorry I didn't see this sooner Mr. Grady...

Usually, if a tropical system encounters a low pressure system, in the form of a frontal
boundary or trof, it will weaken and/or veer it off course. Sometimes though, a trof can help the storm ventilate and strengthen, if it's in the right location relative to the tropical system. High pressure usually provides a steering flow.

Overall, shear and water temperature determine the strength of the system. African dust is also believed to play a role in hurricane strength and development.

Hope this helps.

My new avitar is of my cat, "Max." I work in the insurance industry, but I am interested in healthcare, (I worked as an EMT for St. Louis EMS from 1984-1989 and was in the field for over 10 years) social welfare issues, (I have a bachelor's degree in Social Work from UMSL) politics, religions of all sorts and racial and cultural relations. I have a new cat named "Max" whom I picked up from the animal shelter. He is a younger version of "Socks" my old cat. I enjoy Classical and Jazz Music, although I cannot read music nor play any instrument. I love baseball, but I am not athletic. I love to watch the weather and even watch the NOAA weather radars while at work. Weather is sort of a hobby of mine. I am a "healthy skeptic" when it comes to politicians and all things political.
