How To Move The Jetstream

(note: excerpts from


What is a Jet Stream Solar Power Satellite?

The Jet Stream Solar Power Satellite is a dual use Satellite which can focus microwave energy into a jet stream to change the jet streams locations and prevent from remaining stationary for a long period of time.

How can the Jet Stream Solar Power satellite Change The Direction of a Jet Stream?

The Jet Stream Solar Power Satellite can change the direction of a jet stream. It does this by triggering turbulence in the flowing air which decreases the flow velocity of an edge region of the flow and generating a pressure differential that changes the direction of the bulk air flow.

Jet Stream Characteristics

Flow Pattern

The wind patterns of a jet stream flowing over North America are depicted as arrows. The length of the arrow is proportional to the wind velocity.

This is a typical “kinked” pattern, that can lead to floods or droughts if it doesn't move over long periods of time.

Jet Stream Cross Section

The diagram (at left) is a cross section through a typical jet stream. Kt. is knots. The small central region is the Jet Streak that play a large role in storm development.

Jet Stream in 3D

The drawing (at right) is a schematic of a jet stream in 3D. This shows a jet stream with respect to a developing depression.

Heating Rates in Air

The figure (at left) indicates the heating rates for potential temperature at various altitudes for a Jet Stream Solar Power Satellite focusing its power on the atmosphere at a flux of 1 Megawatt/m^2.

The absorption coefficient at this frequency is 6 dB per km in STP air. The MTG computer code is used to calculate these heating rates.

Options for Heating Profiles

The phased array microwave beam transmitting power from the Jet Stream Solar Power Satellite will be designed to focus and steer the beam in specific patterns on the atmosphere. The nature of a phased array is that it can be electronically “steered” in real time.

This means a specific region of the jet stream could be heated and the heating area could move with the jet stream to keep a given volume of air at a constant heating rate.

Clear Air Turbulence (CAT)

Clear-air turbulence (CAT) sometimes colloguially reffered to as “air pockets” is the erratic movement of air masses in the absence of any visual cues, such as clouds.

Clear-air Turbulence is caused when bodies of air moving at widely different speeds meet; at high altitudes (7,000-12,000 metres/23,000-39,000 feet).

This is frequently encountered around jet streams or sometimes near mountain ranges.

Clear-Air Turbulence is impossible to detect either with the naked eye or with conventional radar, meaning that it is difficult to avoid.

However, it can be remotely detected with instruments that can measure turbulence with optical techniques, such as scintillometers or Doppler LIDARS.

Microwave Beam Heating as Trigger of Clear Air Turbulence

The principal method of this idea, is to utilize microwave power from a solar power satellite to selectively heat a critical region of the jet stream and trigger clear air turbulence that can draw energy from the flow of the jet stream itself, effectively amplifying the use of the microwave power.

Safety Considerations

The microwave beam is primarily absorbed in the air and thus will not be an issue on the ground.

However, it will generate clear air turbulence and also could have major effects on the earth's weather.

We are aware of the tremendous issues involved and recommend that the National Academy of Sciences recommendations for weather modification research in response to global warming is followed.
