Yes that is the primary disadvantage of visible satellite imagery.
photosphere
Meteorologists get the image of a hurricane from satellite photos. By putting several hours of satellite pictures into motion, they can gather information on the track and development of the tropical cyclone.
too dark
Track its direction, and estimate its strength.
Its a Light Microscope! (=
You can't. Tornadoes descend from thunderstorms, and so cannot be seen from above. You can, however, see the thunderstorms in a satellite image. See the link below for a satellite time lapse of storms tha produce tornadoes.
Photos taken of Earth from an orbiting satellite
Quite simply, a visible image is an image that is clear and perfectly able to be seen through the naked eye.
The satellite image taker?
Magnification is the amount by which the image you see will be larger than the actual object, ie. if the image you see appears to be twice as large as the original object then it will be a 2x magnification. (magnification = size of image / size of object) Resolution is the smallest possible visible thing on the enlarged image. On a satellite picture the resolution may be 1m2 meaning that anything smaller is not visible on that picture. In the case of an electron microscope, for example, anything smaller than 1 electron will not be visible using the electron microscope.
The satellite image shows topography, natural and manmade features without political borders.
The satellite image will have more realistic surface of the Earth compared to photograph.

Pixels
Visible images are only of use when taken during daylight hours because they require sunlight to make the image exposure. Infrared images relies on temperature differences to distinguish between objects and can be taken at night or daytime.
Satellite imaging. If you superimpose a satellite image of the Earth at a specific point with a satellite image of air pressure, and then expand those two images forward in time, you can get a decent estimate of what the whether is and is going to be at that point.
