Typhoons and other tropical cyclones are steered by large scale wind patterns, which are mostly determined by high and low pressure systems. High pressure systems, which circulate clockwise in the northern hemisphere tend to cause typhoons to make right turns while low pressure systems, which have counterclockwise winds cause them to make left turns. (This is reversed in the southern hemisphere, but storms there are not called typhoons). There is a semipermanent subtropical ridge of high pressure which causes many typhoons to start out moving west and then to turn north and east. The strength of these winds are what determines the speed of these winds. In the absence of such steering winds typhoons will move slowly and can even become stationary. Slow moving storms such as this tend to have erratic paths.
Since a typhoon is a low pressure system in the northern hemisphere its winds will always rotate counterclockwise.The speed of the winds are determined by a number of factors that influence intensity. A typhoon will tend to strengthen when it is over warm water in a mass of moist air and there is little to no wind shear (i.e. there is little difference between the speed and direction of upper and lower level winds). A typhoon will weaken and possibly dissipate if it moves over land or cold water or if it encounters dry air or strong wind shear.
What else can I help you with?
Which of these would change the direction of an object but not affect the object's speed?
Changing an object's direction without affecting speed requires a force that acts perpendicular to the object's velocity, such as centripetal force or gravitational force. This force causes the object to change direction while continuing at a constant speed. Other forces acting parallel to the object's velocity can change its speed as well as its direction.
Why acceleration produces at constant speed?
Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
Do cyclones go in reverse?
Cyclones only turn in one direction, and do not change mid-cyclone. In the southern hemisphere, cyclones rotate in a clockwise direction. In the northern hemisphere, cyclones (known as hurricanes or typhoons, depending on their location) rotate in an anti-clockwise direction.
Why does the change in the speed of light change its direction while in water?
It seems to me that, to understand that, you need an understanding of the Huygens-Fresnel principle. Check the corresponding Wikipedia article; it has a nice illustration that shows how refraction is derived from this principle.
How the equqtion of motion for an object moving with a uniform velocity change?
Any change in motion (direction or speed) is a change in velocity.Velocity is a vector quantity which means that it has a magnitude and a direction.
What causes light to change directions?
The change in speed of light changes the direction.
Anything that causes and object to move or change its speed or change its direction is called what?
A force.
Every push or pull that causes a change in speed or direction is a?
work
Why does a golf ball accelerates when either if speed or direction changes?
A change in speed or direction of a golf ball causes a net force to act on it. According to Newton's second law of motion, this net force results in an acceleration of the golf ball in the direction of the applied force. This acceleration causes the golf ball to speed up or change its direction.
Why do waves change speed and direction?
Waves change speed and direction when they encounter changes in the medium through which they are moving. This can be due to variations in the density, temperature, or composition of the medium. The interaction causes the wave to refract, reflect, or diffract, leading to changes in its speed and direction.
Force can cause an object to change its speed and or direction?
yes, because force is a push or pull, so an example would be that wind (the force) pushed the bike faster toward a building and steered the bike around the building, which causes the bike to change direction. This is an example of velocity too. Velocity is speed in a specific direction.
What causes a wave to bend and travel in new direction when it moves from one medium to another?
A change in speed of the wave due to the change in medium causes the wave to bend and change direction. This change in speed is a result of the wave moving from a medium with one optical density to another with a different optical density, leading to refraction.
What is force and how is it measured?
In physics, a force is any influence that causes a free body to undergo a change in speed, a change in direction, or a change in shape.

What causes an object to change speed of the direction of motion?
A force acting on the body, along its line of motion.
Forces can change the what of movement of an object?
Forces can change the speed, direction, or both speed and direction of movement of an object.
