WMFG 4.0 TALL PUMPS | LESS PUMPING is MORE FUN | PRESSURE GAUGE | MULTI NOZZLE ATTACHMENTS  It's the original, the disrupter, the best pump, and it's now back in stock! The WMFG 4.0 Tall Pumps are here in stock and ready to ship!  Everyone loves the WMFG 4.0 tall pumps because they are in fact taller than standard stock pumps allowing for less bending down and less pump strokes to pump up your massive light-wind kites as well as the option for either maximum  volume (more air flow) on up and down strokes, or maximum pressure (for when the kite is mostly pumped...

Wind gusts are sudden, brief increases in wind speed that occur over a short period of time, typically a few seconds to a minute. They can be caused by a variety of factors, including: Topography: Local topography, such as hills, mountains, or buildings, can cause gusts as wind is funneled or deflected around these obstacles. This can create sudden changes in wind speed and direction, leading to gusts. Thermal effects: Differences in temperature can create pressure differences in the atmosphere, leading to wind gusts. For example, when the sun heats up the ground, the air above it rises and is...

Wind models are mathematical algorithms used to predict wind behavior in different areas. These models are used in a variety of fields, including meteorology, aviation, and marine transportation, to make predictions about wind speed, direction, and gusts. There are a variety of different wind models that have been developed over the years. Some of the most common ones include: Global models: These models use complex algorithms to predict wind behavior on a global scale. They take into account a variety of factors, including temperature, pressure, and the rotation of the Earth, to create a comprehensive model of wind behavior around...

WMFG revolutionized the kite market with the release of the WMFG 1.0Tall kiteboard pump, dual-action, extra volume, less bending over, less pumping.  Every other kite manufacturer followed suit by copying the 1.0 Tall pump.  But now WMFG is putting out the WMFG 1.0 Pro pump.  It's a double barrel 24.75" tall by 11.5" wide (dimensions to help plan your travel packing) triple action pump capable of up to 25 psi!  Two 1.8L barrels produce 3.6L air volume per stroke.  With the triple-action allowing for double-action (up down pumping), single-action (air only comes out on the down stroke) and single barrel...

The Venturi effect is a phenomenon that occurs when a fluid, such as air, is forced to flow through a narrow channel or constriction in a pipe. As the fluid moves through the narrow section, its speed increases and its pressure decreases. This effect can lead to an increase in wind speed in certain situations. In the case of wind speed, the Venturi effect can occur when wind is forced through a narrow channel, such as a canyon or a gap between buildings. As the wind flows through the channel, its speed increases and its pressure decreases, according to the...
