Active Thunderstorm season continues in Tamil Nadu, Will Chennai join the party?

The active thunderstorm season continues to hold Tamil Nadu firmly under its grip.  On Tuesday the daily mean rainfall for Tamil Nadu & Pondy crossed 10 mm for the 3rd time since 1st of June taking the overall rainfall for the season 2% above normal. The trend continued yesterday as well with many parts of the state receive rains with parts of Tiruvannamalai, Vellore, Salem & Krishnagiri districts getting good rains.

While rest of Tamil Nadu enjoys the rains Chennai has been seeing thunderstorms in bits and pieces.  The irony in all this is Puzhal about 15 kms aerially from the city center recorded 54 mm of which 47 mm fell in one hour during the evening thunderstorms that played hide and seek with Chennai.  Today morning was once again similar story with the storms bypassing Chennai moving about 40 kms to the North and staying stationary for nearly one hour over the Pulicat and Ponneri areas.

There is a fair bit of upper level moisture available over Peninsular India which is allowing these storms to sustain for longer periods and move for larger distances despite the poor wind speeds due to the monsoon nearly shutting down over South India.  The Mid Tropospheric winds being Southerlies / Southeasterlies is also helping the storms to develop creating favorable shear environment in addition to providing additional moisture.

But luck indeed could finally favor Chennai today with possibly some late night thunderstorms heading for the city with some favorable wind pattern.  As has been the case the wind speeds are going to be slow and the thunderstorms are expected to move very slowly which could mean moderate to heavy spells in those lucky places like how Puzhal got yesterday.

Things look good for the stretch between Pondy & SHAR along with Kanchipuram, Tiruvallur districts and adjoining parts of South AP to get some late night thunderstorms. Keeping fingers crossed for Chennai.

    Good morning.
    Erode received rains yesterday.
    Cool and cloudy morning.

  • METEOROLOGICAL WINDS

    This covers the geostrophic wind, surface wind, gradient wind, sub and supergeostrophic winds and the cyclostrophic wind.

    THE GEOSTROPHIC WIND

    – The geostrophic wind is the wind flow that occurs in the middle latitudes aloft in the troposphere.

    – The winds have a more difficult time obtaining geostrophic balance in the equatorial latitudes since the Coriolis force is weak.

    – The geostrophic balance also does not occur at and near the surface since the force of friction is significant there and the geostrophic balance does not occur in a curved flow since a centrifugal force is introduced in that situation.

    – What the geostrophic wind includes is a balance between the PGF (Pressure Gradient Force) and the Coriolis force.

    – This flow results in the wind staying parallel to height contours. The PGF is the force resulting in the pressure difference between higher and lower pressure. The PGF points directly from high to low pressure (or heights).

    – The Coriolis force results from the spin of the Earth and is directed to the right of the path of motion in the Northern Hemisphere.

    – The diagram below shows an example of geostrophic balance in the Northern Hemisphere.

    – The wind flows with higher pressure (heights) to the right of the path of motion and lower pressure (heights) to the left of the path of motion.

    – The PGF points from higher toward lower pressure (heights) and the Coriolis points to the right of the path of motion (which is equal in magnitude but in the opposite direction of the PGF in order to balance it).

    – The height contour spacing determines the magnitude of the wind. Closer spacing results in stronger wind.

    THE SURFACE WIND

    – The surface wind is the balance of forces on the wind that occurs at and near the Earth’s surface.

    – The contrast to the geostrophic wind is that the surface wind introduces the force of friction.

    – In the diagram below labeled (1) we start with geostrophic balance and introduce friction.

    – Friction is a force that slows the wind and this is why the friction vector is in the opposite direction to the resulting wind labeled on (2).

    – When friction slows the wind it causes a reduction in the Coriolis force since the magnitude of the Coriolis force is directly related to the wind speed.
    – Although the Coriolis force decreases, the Pressure Gradient Force (PGF) stays the same.

    – This results in an imbalance between the Coriolis and Pressure Gradient Force. The PGF has a greater magnitude as compared to Coriolis.

    – This results in the wind crossing the isobars at an angle from higher pressure toward lower pressure.

    – In the diagram (2), it shows the balance of the forces between Coriolis, friction and PGF along with the resulting wind.

    – The result is that at the surface, air flow convergences into low pressure systems and divergences from high pressure systems.

    THE GRADIENT WIND

    – The gradient wind is a balance of the Pressure Gradient Force, centrifugal and Coriolis.

    – A geostrophic wind becomes a gradient wind when the wind begins flowing through curved height contours.

    – The curving motion introduces a centrifugal (outward fleeing) force. The centrifugal effect can be felt when turning through a curve in a car.

    – You stay with the car but it feels like you are being pushed sideways.

    – The gradient wind occurs aloft (no friction) within curved height contours.

    – The wind stays parallel to the height contours throughout the curve. The two examples below will be used to show how the flow stays parallel to the height contours. In the first diagram below (the trough), the outward fleeing centrifugal force is pointing in the same direction as the Coriolis (Northern Hemisphere, Coriolis is to right of path of motion).

    – PGF must balance both centrifugal and Coriolis. For this to happen, the Coriolis needs to shorten so that Coriolis + centrifugal stays equal to the magnitude of the PGF.

    – Since the Coriolis decreases, the wind speed decreases. This allows the wind to stay parallel to the height contours. Without this wind speed reduction the wind would follow a more straight line path that would cause it to move from lower toward higher height contours.

    – Another way to think of this is that the PGF is greater in magnitude than the Coriolis thus the wind is going to bend more in the direction of PGF and this causes the flow to stay parallel to the height contours.

    – In the second diagram below (the ridge), the outward fleeing centrifugal force is pointing in the same direction as the PGF (Northern Hemisphere, to left of path of motion).

    – PGF and centrifugal must balance Coriolis (Northern Hemisphere, Coriolis is to right of path of motion).

    – For this to happen, the Coriolis needs to get longer so that Coriolis = centrifugal + PGF. Since the Coriolis increases, the wind speed increases. This allows the wind to stay parallel to the height contours.

    – Without this wind speed increase the wind would follow a more straight line path that would cause it to move from higher toward lower height contours.

    – Another way to think of this is that the Coriolis is greater in magnitude than the PGF thus the wind is going to bend more in the direction of Coriolis and this causes the flow to stay parallel to the height contours.

    SUBGEOSTROPHIC AND SUPERGEOSTROPHIC WIND

    – The information here is an extension of the previous explanation on the “Gradient Wind”.

    – A gradient flow through a trough is termed “subgeostrophic”. The “sub” means the wind speed is less than what would be expected if the wind was geostrophic.

    – In the first example below (“subgeostrophic wind”), the wind is flowing through a trough. In this diagram below (the trough), the outward fleeing centrifugal force is pointing in the same direction as the Coriolis (Northern Hemisphere, Coriolis is to right of path of motion).

    – PGF must balance both centrifugal and Coriolis. For this to happen, the Coriolis needs to shorten so that Coriolis + centrifugal stays equal to the magnitude of the PGF.

    – Since the Coriolis decreases, the wind speed decreases. This allows the wind to stay parallel to the height contours.

    – Without this wind speed reduction the wind would follow a more straight line path that would cause it to move from lower toward higher height contours.

    – Another way to think of this is that the PGF is greater in magnitude than the Coriolis thus the wind is going to bend more in the direction of PGF and this causes the flow to stay parallel to the height contours.

    – A gradient flow through a ridge is termed “supergeostrophic”. The “super” means the wind speed is greater than what would be expected if the wind was geostrophic.

    – In the second diagram below (“supergeostrophic flow”), the outward fleeing centrifugal force is pointing in the same direction as the PGF (Northern Hemisphere, to left of path of motion).

    – In this example the wind is flowing through a ridge. PGF and centrifugal must balance Coriolis (Northern Hemisphere, Coriolis is to right of path of motion).

    – For this to happen, the Coriolis needs to get longer so that Coriolis = centrifugal + PGF. Since the Coriolis increases, the wind speed increases. This allows the wind to stay parallel to the height contours.

    – Without this wind speed increase the wind would follow a more straight line path that would cause it to move from higher toward lower height contours.

    – Another way to think of this is that the Coriolis is greater in magnitude than the PGF thus the wind is going to bend more in the direction of Coriolis and this causes the flow to stay parallel to the height contours.

    – The point of this discussion is that the wind flows slower through troughs and faster through ridges when height contour spacing is the same for each. In reality, the height contour spacing is typically much closer together in a trough. Thus, in reality, wind speed is stronger in troughs since the Pressure Gradient Force is typically much higher in troughs.

    THE CYCLOSTROPHIC WIND

    – The cyclostrophic wind differs from the gradient wind in that the Coriolis force is not involved.

    – The Coriolis force requires long time periods (hours) in order to become firmly established. Rotations that occur in the time scale of minutes or less will not be significantly influenced by Coriolis.

    – The cyclostrophic wind is a balance between the Pressure Gradient Force (PGF) and the outward fleeing centrifugal force. A cyclostrophic wind also tends to have a “tight” curvature compared to curvatures within troughs and ridges.

    – This occurs since the wind motion is not only over short time scales but also over much shorter distance scales. Examples of cyclostrophic weather events include circulations within thunderstorms, tornadoes and wind eddies.

    – A cyclostrophic circulation can result in a brief but rapid drop in surface pressure due to the rising motions these circulations can produce.

    CONVECTIVE EROSION OF CAP – Learning and Understanding Weather

    – This addresses one process that can erode a cap and that is the process of solar heating of the boundary layer.

    – In the diagram below the boundary layer is the “unstable layer” labeled at the surface.

    – This layer is made unstable by solar energy warming the ground which is turn warms the air above it creating a significant temperature decrease with height within the boundary layer.

    – Within this unstable layer, air will convectively rise. With enough moisture present, fair weather cumulus will develop.

    – In this diagram, fair weather cumulus are forming instead of storm producing cumulus since there is a capping layer above the boundary layer.

    – The capping layer is a layer of warmer and thus stable air aloft that prevents the penetration of convective elements through it.

    – When the cumulus enters the capping layer, its vertical uplift slows and ceases within the capping layer.

    – A capping layer can make the differences between fair weather and stormy weather.

    – As convective elements try to penetrate the capping layer one after another it will cause the capping layer to weaken.

    – If the capping layer can be weakened enough then it will eventually break.

    – Convective elements that try to penetrate the capping layer result in the capping layer weakening.

    – One reason this occurs is because moisture from the clouds is introduced into the capping layer.

    – The evaporation of cloud droplets within the capping layer results in a cooling of the capping layer.

    – Another reason is because some of the air from the boundary layer is mixed with the capping layer air.

    – Thus the capping layer is losing mass due to getting mixed out with the unstable boundary layer below it.

    – This process is typically most evident in the afternoon when solar heating is at a maximum and convective elements are bombarding the capping layer.

    – When a cap breaks it will often occur in the afternoon when cumulative solar heating and convective motions are maximized.

    – Once a convective element is able to penetrate the capping layer then it can rise through the unstable air that is above the capping layer.

    – This results in deep convective storms. If the cap is very strong, then solar heating and convective motions in the boundary layer may not be able to break it.

    – This situation can result in a “bust” in convective storms if it was previously expected that the cap would break in the afternoon.
