The howling sound you are hearing is most likely your alternator failing. When it starts to make this kind of sound, this is a sign of the bearings inside beginning to fail (hence the whining noise) or the diodes inside failing which is what will cause it to also fail to charge the battery correctly. You are driving on borrowed time right now and should have this fixed very soon as it is only a matter of time before it fails completely. If you need help with this repair, I would recommend having an expert form YourMechanic come to your location to diagnose and replace your alternator as necessary.
